📋 Clinical Stem — Chronic Insomnia
A 44-year-old woman requesting sleeping tablets for 6 months of insomnia after a difficult period at work
Priya Sharma attends requesting "something to help me sleep." She is a secondary school teacher, 44, with a 6-month history of insomnia triggered by a difficult inspection period at work. The inspection is over but the sleep problem has persisted: she lies awake for 1–2 hours at sleep onset, wakes frequently around 3am, cannot return to sleep, and feels unrefreshed despite 6–7 hours in bed. Daytime consequences: fatigue, concentration difficulties, and irritability affecting her teaching. She has tried sleep hygiene advice from the internet with limited success. Her GP last year prescribed zopiclone 7.5mg for 2 weeks "for a bereavement" — she found it helpful and has self-purchased a private online prescription twice since (she does not volunteer this). She does not have OSA symptoms but her husband has mentioned snoring. She drinks 2 glasses of wine most evenings "to help her wind down."
This stem tests five key clinical skills: recognising chronic insomnia disorder and its perpetuating factors (hyperarousal, dysfunctional sleep beliefs, compensatory behaviours including alcohol); discussing CBT-I as NICE first-line treatment rather than issuing hypnotics; identifying the zopiclone misuse pattern (online prescriptions, escalating use) without damaging the therapeutic relationship; screening for OSA (snoring mentioned by partner); and exploring alcohol as a sleep aid (initially promotes sleep onset but disrupts sleep architecture, worsening the 3am waking). The request for sleeping tablets is explicitly not automatically fulfilled.
Scenario A — Elderly Patient with Insomnia 72-year-old man on zopiclone 7.5mg nightly for 3 years, requesting repeat prescription. Key issues: Z-drug long-term use in elderly (NICE NG215: avoid; fall risk; cognitive impairment; next-day sedation); deprescribing using gradual dose reduction; Circadin 2mg MR as safer alternative for age ≥55; CBT-I adapted for older adults. Explore reason for original prescription — often prescribed for grief, hospital admission, or acute stress and never reviewed.
Scenario B — Insomnia in Pregnancy 28-year-old woman, 20 weeks pregnant, not sleeping — sleep fragmentation, restless legs, bladder urgency, anxiety. Sleep hygiene adaptations for pregnancy; iron deficiency screen for RLS (ferritin — supplement if below 50 mcg/L); no hypnotics in pregnancy; CBT-I safe; lateral decubitus position; pregnancy pillow. Restless legs syndrome: dopaminergic (in third trimester — reassess postnatally).
Scenario C — Insomnia Secondary to Depression 38-year-old man with 4-month insomnia, waking at 3–4am, unable to return to sleep. Early morning wakening (EMW) is a biological marker of depression. Screen with PHQ-9. NICE: treat the underlying depression — antidepressant choice matters (sertraline is activating: give in morning; mirtazapine is sedating: useful in depression + insomnia; give at night). Hypnotics for depression-related insomnia are not first-line.
Scenario D — Shift Worker with Insomnia 35-year-old nurse on rotating shifts. Circadian rhythm sleep-wake disorder (shift work type). Sleep hygiene for shift workers: blackout curtains; earplugs; schedule sleep immediately after shift. Melatonin for circadian resetting (off-label for shift work). Strategic napping. Light therapy (morning light to advance sleep phase; avoid evening light). Occupational health involvement for persistent cases.
Scenario E — Zopiclone Dependence and Deprescribing 51-year-old woman on zopiclone 7.5mg nightly for 18 months requesting repeat prescription. Dependence features: rebound insomnia on stopping; dose escalation; obtaining from multiple sources. Gradual dose reduction schedule: 7.5mg → 3.75mg → alternate nights → stop over 4–12 weeks. CBT-I alongside taper. Melatonin for bridging in age ≥55. Warn about rebound insomnia (temporary; not relapse of original problem).
Key variables to adapt for Age (Circadin for ≥55; Z-drugs avoid in elderly), pregnancy, psychiatric comorbidity (depression/anxiety — treat underlying condition), OSA (CPAP not hypnotics), alcohol as self-medication (disrupts sleep architecture), occupational driving (DVLA duty if EDS), and previous zopiclone prescriptions (escalation pattern, online prescriptions, dependence risk).

History Taking — Open Question · Sleep Architecture · Perpetuating Factors · Red Flags · ICE
collapse
The insomnia history has one structural imperative: understand the perpetuating factors, not just the precipitating trigger. Most insomnia begins with an identifiable stressor (the "P" in the 3P model: predisposing, precipitating, perpetuating). The precipitant often resolves, but the insomnia persists because of hyperarousal (the bed becomes associated with wakefulness not sleep) and compensatory behaviours (lying in, napping, alcohol as a sleep aid) that maintain the problem. CBT-I targets these perpetuating factors — identifying them in the history makes the treatment rationale compelling and relevant to the patient.
🎓 SCA framing — acknowledging the request before exploring the need
"I can hear that the sleep problem has been making things really difficult for months, and I absolutely want to help. Before I talk about what we can offer, I would like to understand the sleep problem in more detail — because the most effective treatment is one that is matched to the specific pattern of your insomnia rather than a single solution for everyone. Would that be okay?"
This framing acknowledges the patient's expectation (a prescription) without promising it, creates space for a more thorough history, and introduces the concept that treatment is individualised — which is both true and reduces the risk of a confrontational response if a hypnotic is not immediately prescribed.
1A — Characterising the sleep problem: the three domains
QuestionWhy it matters clinicallyChanges what?
🟢 OPEN QUESTION"Tell me about the sleep problem — what does a typical night look like for you from the moment you get into bed to the moment you get up?" The narrative distinguishes the three insomnia subtypes before any targeted questioning is needed. Sleep-onset insomnia (lying awake >30 min before sleep: hyperarousal, anxiety, poor sleep hygiene); sleep-maintenance insomnia (waking in the night and being unable to return to sleep: most commonly hyperarousal or early morning awakening of depression); early morning awakening (waking 1–2 hours before desired wakeup time and being unable to return to sleep: biological marker of depression or circadian phase advance in elderly).In SCA: the candidate who asks "how long do you lie awake?" before allowing the patient to describe their night spontaneously has missed both the open narrative and the psychosocial context that makes CBT-I relevant and acceptable. Onset vs maintenance vs EMW: changes managementPsychosocial trigger; perpetuating factors
Sleep-onset latency (SOL)"When you get into bed, how long does it typically take you to fall asleep? What goes through your mind while you are waiting?"SOL >30 minutes on ≥3 nights/week is the diagnostic threshold for sleep-onset insomnia. The content of the mind during SOL is diagnostically important: racing, ruminative thoughts (primary insomnia / anxiety); worrying thoughts about not sleeping ("if I don't sleep I won't cope tomorrow" — sleep-specific anxiety); intrusive thoughts (trauma; PTSD); no specific thoughts but physical hyperarousal (conditioned arousal — the bed has become a wake-promoting stimulus).The "conditioned arousal" pattern — lying in a comfortable bed, feeling completely unable to sleep — is pathognomonic of chronic primary insomnia and is the most important target of CBT-I stimulus control intervention.SOL >30 min → sleep-onset insomnia; conditioned arousalStimulus control; sleep restriction therapy (CBT-I components)
Night wakings and duration"How many times do you wake in the night? How long are you awake for? What time do you typically wake up and can you return to sleep?"Sleep-maintenance insomnia: wakings >30 min; especially 3–4am wakings that are impossible to return from. This pattern is common in anxiety disorders (hyperarousal) and depression (early morning awakening). Alcohol-induced sleep fragmentation: alcohol shortens the first sleep cycle but then produces rebound arousal in the second half of the night — causing the 3am waking Priya describes. Sleep-disordered breathing: OSA causes fragmented, non-restorative sleep without the patient necessarily being aware of the cause.3am waking specifically is a high-yield clinical pointer to: (1) alcohol as a sleep aid (rebound arousal from metabolism of alcohol); (2) depression (early morning awakening); or (3) OSA (oxygen desaturation events). All three require different management from primary insomnia.3am waking → alcohol, depression, or OSA; each has different managementAlcohol reduction; PHQ-9; STOP-BANG respectively
Total sleep time and time in bed"What time do you typically get into bed? What time do you wake up for the day? How many hours of sleep do you estimate you actually get?"Sleep efficiency = (total sleep time / total time in bed) × 100. Normal sleep efficiency >85%. Insomnia paradox: many patients with insomnia spend 8–9 hours in bed but sleep only 4–5 hours — sleep efficiency 50–60%. Compensatory bed extension (staying in bed longer to "catch up") perpetuates insomnia by diluting sleep drive. Sleep restriction therapy — deliberately reducing time in bed to match actual sleep time — is the most powerful component of CBT-I and the one that most counterintuitively improves insomnia.Sleep restriction therapy feels counterintuitive to patients: "you want me to sleep less to sleep better?" Explaining the mechanism (consolidated sleep drive; rebuilding the association between bed and sleep) is essential for adherence.Sleep efficiency <85% → sleep restriction therapy (CBT-I)Excess time in bed → perpetuating factor to target
Daytime impact"How does the poor sleep affect you during the day — your energy, concentration, mood, driving, work, relationships?"Daytime functional impairment is both a diagnostic criterion (ICSD-3 / DSM-5: sleep difficulty + daytime impairment = insomnia disorder) and a risk-stratification tool. Driving with severe daytime sleepiness is a DVLA notification issue — the GP has a legal duty to advise the patient to notify DVLA if their ability to drive is impaired. Work impairment provides the motivational framing for engaging with CBT-I: "treating your insomnia will directly improve your performance in the thing that matters most to you."Cognitive impairment from poor sleep is often underestimated — insomnia reduces processing speed, working memory, and decision-making capacity in ways that are equivalent to mild alcohol intoxication. Naming this specifically helps the patient understand the clinical urgency of treatment.Daytime impairment: motivational framing for CBT-IDriving impairment: DVLA notification duty
Sleep hygiene and behaviours"Tell me about your habits around sleep — what time you go to bed, screens, caffeine, alcohol, exercise, temperature, what you do if you cannot sleep."Perpetuating behaviours are the engine of chronic insomnia. Key perpetuating factors to identify: (1) Alcohol as a sleep aid — initially sedating but produces rebound arousal; disrupts REM sleep; worsens 3am waking; tolerance develops rapidly; (2) Screen use in bed — blue light suppresses melatonin; content causes arousal; bed becomes associated with wakeful activities; (3) Compensatory napping — reduces homeostatic sleep drive needed for night-time sleep; (4) Irregular sleep timing — disrupts circadian rhythm; (5) Lying in after poor night — extends time in bed; reduces sleep drive further; (6) Clock-watching — amplifies anxiety about duration of waking.The alcohol-as-sleep-aid pattern requires sensitive exploration: many patients do not conceptualise their evening wine as problematic because it does help them fall asleep. The clinical explanation ("it helps the first half of the night but causes the waking you experience in the second half") is often the most illuminating thing a GP tells an insomnia patient.Alcohol reduction; stimulus control; sleep hygiene programmePerpetuating factors identified → CBT-I targets defined
Duration and onset"When did this start? Was there something that triggered it? How has it changed over the months?"The 3P model (predisposing, precipitating, perpetuating): predisposing factors (personality traits: perfectionism, tendency to ruminate; family history of insomnia; female sex — higher risk); precipitating factors (work stress, bereavement, illness, relationship difficulty — the "trigger event" that often resolves while insomnia persists); perpetuating factors (the behaviours and beliefs that maintain insomnia after the trigger has gone — these are the treatment targets). Chronic insomnia: ≥3 months, ≥3 nights/week, with daytime impairment.A patient whose trigger has resolved but whose insomnia persists is a perfect CBT-I candidate — the treatment rationale is directly applicable: "the original problem has gone, but some habits have formed during that period that are keeping the sleep problem going. CBT-I specifically targets those habits."Precipitant resolved → perpetuating factors dominant → CBT-I ideal candidate
Comorbid conditions"Do you have any conditions that might affect sleep — pain, breathlessness, nocturia, reflux, restless legs, anxiety, depression?"Secondary insomnia (insomnia as a symptom of another condition) requires treating the underlying cause alongside sleep-specific interventions. Major medical causes: OSA (the most important to exclude), chronic pain, GERD, heart failure (orthopnoea), nocturia (cardiac, prostate, diabetes), RLS (dopaminergic; iron deficiency relevant). Major psychiatric causes: depression (EMW), anxiety (hyperarousal, SOL), PTSD (nightmares, hypervigilance), bipolar (sleep changes are early episode marker).NICE NG215 (2022) moved away from the primary/secondary distinction — it now recommends treating insomnia as a clinical entity in its own right even when comorbid conditions exist, because treating the comorbid condition does not reliably resolve the insomnia, which has its own perpetuating mechanisms.OSA → STOP-BANG; CPAP not hypnotics. Depression → PHQ-9; antidepressant choice. RLS → iron, dopaminergic agentTreat comorbidity AND insomnia separately per NICE NG215
Medication and substance history"Are you taking anything for sleep at the moment — prescribed, over the counter, or online? Any caffeine, alcohol, or other substances? Any prescribed medication that might affect sleep?"Hidden hypnotic use (online prescriptions, borrowed tablets, OTC antihistamines) is common and must be actively screened for. Z-drug escalation (increasing dose, frequency, or duration beyond prescription) indicates dependence and requires a deprescribing plan alongside CBT-I. Medication causes of insomnia: SSRIs (activating; give in morning), beta-blockers (nightmares, reduced melatonin), corticosteroids (arousal), decongestants, theophylline, stimulants. Caffeine: half-life 5–7 hours; a 3pm coffee affects 3am sleep.The patient who has been self-prescribing zopiclone online needs a non-judgmental, curious approach: "I want to understand what has been helping and what hasn't — tell me about the zopiclone you mentioned." The aim is to complete a dependence screen without the patient feeling accused of drug-seeking.Z-drug dependence: deprescribing plan; CBT-I. Caffeine: limit after midday. Activating medications: timing adjustmentMedication-induced insomnia: adjust timing not dose
OSA screen (active)"Does your partner mention snoring? Any gasping or stopping breathing? Do you wake with a dry mouth or headache? How sleepy are you in the daytime — could you fall asleep in a quiet room or at traffic lights?"OSA is the most important condition to exclude in insomnia — treating OSA insomnia with hypnotics is dangerous (respiratory depression). STOP-BANG screen at every insomnia consultation. Risk factors: male sex, overweight/obese, collar size >16 inches, ≥50 years old, hypertension, crowded airway. Partner report is often the most sensitive OSA indicator. Epworth Sleepiness Scale (ESS): >10 = excessive daytime sleepiness warranting investigation. ESS >15 = severe EDS; driving hazard; DVLA notification.A patient who presents with "insomnia" may actually have OSA-driven non-restorative sleep — they are spending enough time in bed but not getting restorative sleep stages. These patients often describe non-refreshing sleep rather than inability to sleep. CPAP dramatically improves their sleep quality — hypnotics would mask the problem without treating it and risk respiratory depression.STOP-BANG ≥3 → polysomnography / home sleep studyOSA confirmed: CPAP first; hypnotics avoided

1C — ICE: Ideas · Concerns · Expectations
💡 Why ICE matters in insomnia — addressing the sleeping tablet expectation directly

The insomnia consultation has an almost universal built-in expectation: the patient expects a prescription for a sleeping tablet. They have often exhausted sleep hygiene advice (or believe they have), they are suffering, and they know from experience (or from others' experience) that tablets work. A GP who spends the consultation discussing CBT-I without acknowledging this expectation will encounter resistance, reduced adherence, and a patient who leaves feeling dismissed. The expectation must be explicitly named and addressed — not circumvented.

💭 Ideas
"What do you understand about why the sleep problem has persisted — do you have any sense of what might be keeping it going?"
Common patient beliefs: "I am just someone who doesn't sleep well" (catastrophising); "my brain is broken"; "I need tablets to function." These dysfunctional beliefs about sleep are a specific CBT-I treatment target — identifying them here allows them to be directly addressed in the management plan. The most common dysfunctional belief is "I must get 8 hours of sleep or the day will be ruined" — challenging this is a key CBT-I intervention (cognitive restructuring).
😟 Concerns
"What worries you most about the sleep problem — is it the impact on your work, your health, the fact it won't get better?"
Concerns drive health-seeking behaviour and must be addressed directly. Common concerns: long-term health consequences of poor sleep (fatigue, dementia, cancer — addressed with evidence); addiction to sleeping tablets (legitimate concern; validate it); cost or accessibility of CBT-I; how long treatment will take. The patient who is concerned about addiction is already motivated for CBT-I — they just need to know it exists and is available.
🎯 Expectations
"I want to make sure I understand what you were hoping I could offer today — is it primarily the sleeping tablets, or are you open to hearing about approaches that might work better long-term?"
The patient who is explicitly open to alternatives is straightforward to manage. The patient who is rigidly set on zopiclone requires the GP to explain — with evidence and without judgment — why a short course of hypnotics will not solve a 6-month problem and may make it worse. "The tablets will help for a few nights but your brain will adapt to them within 2–4 weeks, after which they will be less effective and stopping them will temporarily make the sleep worse."
1D — Psychosocial context and perpetuating factors
😟 Hyperarousal — the engine of chronic insomnia

The most important concept in chronic insomnia pathophysiology is hyperarousal: a state of elevated physiological and cognitive arousal that prevents sleep. The bed has been repeatedly associated with wakefulness (lying awake for hours, worrying about not sleeping) and has become a conditioned stimulus for arousal rather than sleep. This is why patients often fall asleep on the sofa but cannot sleep in their own bed.

"Does it sometimes feel like you could fall asleep anywhere — in front of the TV, on the sofa — but the moment you get into bed you are completely awake? That is actually very helpful information because it tells us that your brain has learned to associate the bed with being awake rather than sleeping."
🍷 Alcohol as a Sleep Aid

Alcohol promotes sleep onset (sedating effect) but disrupts the second half of the night through rebound arousal as it is metabolised. REM sleep is suppressed by alcohol — leading to fragmented, non-restorative sleep. Tolerance to the sedating effect develops rapidly (within days to weeks) — the patient needs increasing amounts for the same effect. The 3am waking pattern in a patient who drinks in the evening is highly specific for alcohol-induced sleep fragmentation.

"You mentioned the wine helps you wind down and fall asleep. That makes complete sense — alcohol is genuinely sedating. But here is what happens in the second half of the night: as your body metabolises the alcohol, there is a rebound effect that actually promotes wakefulness. The 3am waking you described is a classic pattern from that. Reducing the alcohol may feel counterintuitive but it is likely to help the second half of your night significantly."
😰 Dysfunctional Sleep Beliefs

Specific beliefs about sleep that perpetuate insomnia: "I must get 8 hours or tomorrow will be ruined"; "I have lost the ability to sleep normally"; "not sleeping will make me ill"; "I am the only person who cannot sleep." These catastrophic beliefs create anticipatory anxiety that increases arousal at bedtime — the very opposite of what is needed. Cognitive restructuring (a component of CBT-I) systematically challenges and replaces these beliefs.

"What goes through your mind when you are lying awake? Do you find yourself thinking things like 'I need to sleep or tomorrow will be terrible'? Those thoughts — however understandable — actually prevent sleep by keeping the arousal system activated."
💼 Occupational Stress and Identity

For a teacher like Priya, performance anxiety has both started (work inspection) and sustained (performance anxiety about sleep itself) the insomnia. The metacognitive cycle: worrying about not sleeping → arousal → not sleeping → confirming the worry → more arousal. This cycle is specifically targetted by CBT-I's cognitive restructuring and mindfulness components.

"You mentioned the sleep problems started during the inspection. The inspection is over now — but it sounds like the sleep problem has taken on a life of its own, almost as if your brain is now worried about the sleep itself rather than the original stress. Is that how it feels?"
📱 Compensatory Behaviours

Behaviours patients use to cope with insomnia that actually perpetuate it: extending time in bed (reduces sleep efficiency); napping (reduces homeostatic drive for night-time sleep); early to bed (insufficient sleep pressure built up); clock-watching (amplifies arousal); screens in bed (arousing content + blue light); trying harder to sleep ("sleep effort" is paradoxically arousing). Every compensatory behaviour is a CBT-I target.

"Do you find yourself staying in bed longer in the morning or going to bed earlier to try to catch up? That is a completely natural response — but it actually reduces the pressure your body builds up to sleep, which makes the next night harder. CBT-I works partly by rebuilding that pressure."
🔮 Health Anxiety about Sleep

The widespread coverage of sleep deprivation's health consequences (cardiovascular disease, dementia, diabetes, obesity) has created significant health anxiety in many insomnia patients. They are worried that their sleep problem is damaging them. Addressing this anxiety — with accurate, proportionate information — reduces the catastrophising that perpetuates hyperarousal. "Short-term insomnia during periods of stress does not cause dementia" is reassuring and accurate.

"Have you been reading about the health consequences of poor sleep? There is a lot of information out there — some of it is accurate and some of it is alarming in a way that is not proportionate. I want to make sure you have an accurate picture, because worry about the health effects of insomnia is itself something that can maintain the sleep problem."

"The wine helps you fall asleep — that makes sense as alcohol is sedating. But the 3am waking you describe is actually a classic pattern from alcohol metabolism: as it clears your system, there is a rebound arousal effect. Reducing alcohol often helps the second half of the night significantly."
"I want to check something important about the quality of your sleep — does your partner mention snoring? [screen for OSA] This matters because if sleep-disordered breathing is present, sleeping tablets would not be the right treatment and could actually cause harm."
"The most effective treatment for insomnia — more effective than sleeping tablets in the long-term — is a talking therapy called CBT-I. I'd like to explain what that involves."

Step 3
Do I Need This Examination?
collapse
Insomnia has no pathognomonic examination findings. Examination is directed by history: OSA risk (BMI, neck circumference, airway, BP); depression or anxiety features; thyroid disease; medications with sedating or stimulating side effects. The primary purpose of examination in insomnia is to identify underlying causes and contraindications to hypnotic medication.
ExaminationWhy it mattersFinding that changes managementChanges?
BMI and neck circumferenceOSA risk factors: BMI >30; neck circumference >40cm (women) or >43cm (men). Obesity is the strongest modifiable OSA risk factor. Weight reduction reduces OSA severity. Baseline BMI relevant if hypnotic prescribed (sedation + weight gain with some agents).BMI >30 + snoring: STOP-BANG elevated; home sleep study. Normal: primary insomnia pathway.YES — OSA risk stratification
Blood pressureHypertension is a risk factor for OSA (and vice versa — OSA causes secondary hypertension). Uncontrolled hypertension is also associated with insomnia directly. Some antihypertensives cause insomnia (beta-blockers: nightmares, reduced melatonin).Elevated BP + snoring: OSA-hypertension cycle; CPAP may reduce BP. Beta-blocker causing insomnia: switch to alternative antihypertensive.Context — hypertension present
Oropharyngeal airway (Mallampati score)Crowded posterior airway, large tonsils, retrognathia are anatomical OSA risk factors. Mallampati III/IV with other OSA features strengthens the referral case. Relevant particularly in patients who are not overweight but have OSA features (structural OSA).Crowded airway + OSA features: refer regardless of BMI. Normal airway + low STOP-BANG: OSA less likely.Context — OSA screen positive
Thyroid assessmentHyperthyroidism: hyperarousal, racing thoughts, palpitations — close mimic of anxiety-driven insomnia. Hypothyroidism: causes fatigue and disrupted sleep architecture (but usually excessive sleep not insomnia). TFTs if clinically indicated by symptoms or goitre.Goitre or tremor: TFTs. Hypothyroid: replace; reassess sleep. Hyperthyroid: treat; reassess.Context — clinical signs of thyroid disease
Mental state examinationDepression: low mood, psychomotor retardation, poor concentration, flat affect — if clinically evident, PHQ-9 is needed and antidepressant choice drives management. Anxiety: restlessness, tremor, autonomic features. PTSD: hypervigilance, startle response.Depressed MSE + early morning awakening: mirtazapine (sedating) or sertraline (morning); NHS Talking Therapies. Anxiety features: GAD management alongside insomnia.YES — psychiatric comorbidity changes management entirely

Examination rationale
"I will check your blood pressure and have a brief look at your weight and your airway — this helps me assess the likelihood of the snoring being significant and whether there is anything physical that needs addressing."
Deductions

Step 4
Do I Need This Investigation?
collapse
Primary chronic insomnia requires no routine blood tests. Investigations are targeted at suspected secondary causes: OSA (home sleep study), depression/anxiety (PHQ-9, GAD-7), hypothyroidism (TFTs), iron deficiency in RLS (ferritin), and alcohol assessment (LFTs, GGT). A sleep diary is the most important "investigation" for insomnia — it objectifies the subjective complaint and provides baseline data for CBT-I.
InvestigationWhen indicatedWhat result changes management
Sleep diary (2 weeks) — primary "investigation"Mandatory for CBT-I — establishes actual sleep timing, SOL, WASO, total sleep time, sleep efficiency, and daytime functioning objectively (or as objectively as possible without actigraphy). Exposes the gap between perceived and actual sleep (patients often underestimate their sleep). Provides baseline for calculating sleep restriction therapy target.Sleep efficiency <85% → sleep restriction therapy calculated. Highly irregular sleep timing → circadian stabilisation first. Total sleep time much greater than perceived → reassurance; reframe sleep perception rather than changing treatment.
PHQ-9 + GAD-7 — for all insomnia presentationsDepression and anxiety are the most common secondary causes of insomnia and are easily missed when the patient presents primarily with a sleep complaint. PHQ-9 question 3 (sleep) and question 1/2 (low mood, anhedonia) distinguish depressive insomnia from primary insomnia. Early morning awakening (EMW) = depression until proven otherwise.PHQ-9 ≥10 → antidepressant + CBT; mirtazapine if sleep very disturbed (sedating). GAD-7 ≥10 → GAD management; CBT for anxiety; NHS Talking Therapies. Both managed alongside CBT-I per NICE NG215.
STOP-BANG + Epworth Sleepiness Scale (ESS) — all insomnia patientsSTOP-BANG: 8-item clinical tool (Snoring, Tired, Observed apnoea, Pressure, BMI >35, Age >50, Neck >40cm, Gender male). Score ≥3: moderate-high OSA risk. ESS >10: excessive daytime sleepiness. ESS >15: severe; driving hazard; DVLA notification. Applied at every insomnia presentation — failure to screen for OSA before prescribing a hypnotic is a clinical error.STOP-BANG ≥3 or ESS >10 → home sleep study; respiratory / sleep medicine referral; NO hypnotics. STOP-BANG <3 + low ESS → OSA less likely; proceed with insomnia management.
TFTs — if clinical suspicion of thyroid diseaseNOT routine. Indicated if: tremor, palpitations, heat intolerance, weight change, goitre, or if insomnia is unresponsive to treatment and no other explanation found. Hyperthyroidism causes hyperarousal and insomnia. Hypothyroidism causes fatigue and disrupted sleep architecture.Hyperthyroidism → carbimazole / propylthiouracil; beta-blocker for acute symptoms; reassess insomnia after normalisation. Hypothyroidism → levothyroxine; reassess.
Ferritin — if restless legs syndrome features presentRLS is associated with iron deficiency (low ferritin depletes dopaminergic pathways in the brain). Ferritin <75 mcg/L in RLS: treat with oral iron supplementation before dopamine agonists. Ferritin <50: definitely supplement. RLS in pregnancy: very common; iron supplementation often adequate.Ferritin <75 → oral iron (ferrous sulphate); reassess RLS at 3 months. Normal ferritin + persistent RLS → dopamine agonist (pramipexole) or gabapentinoids (specialist referral for complex RLS).
LFTs + GGT — if significant alcohol useSignificant alcohol use as a sleep aid: GGT is a sensitive marker of regular alcohol use; LFTs assess hepatic damage. Not indicated for 2 glasses of wine per night but warranted if AUDIT-C elevated, patient denies problem drinking despite escalating use, or if alcohol dependence is suspected.Elevated GGT/LFTs → discuss alcohol use explicitly; AUDIT-C; alcohol brief intervention; CAGE if dependence suspected; hepatology if significant liver disease. Normal: document and review.

Step 5
Reaching a Diagnosis — Explained in Plain Language
collapse
Explaining the diagnosis of chronic insomnia — using the 3P model and the conditioned arousal concept — is itself therapeutic. Patients who understand why they have insomnia and how CBT-I works are significantly more adherent to treatment than those who receive a diagnosis without an explanation.
🗣️ Explaining Chronic Insomnia in Plain Language — the 3P Model

"Sleep works a bit like hunger — the longer you are awake, the more sleep pressure your body builds up, and eventually sleep happens. When something stressful happens — like your inspection — your brain's alarm system activates, and that alarm system is designed to keep you alert in a crisis. The problem is that the alarm system does not automatically switch off when the crisis is over. And in the meantime, some habits have formed: lying awake in bed for hours, watching the clock, the wine at night, staying in bed longer to catch up. Each of these habits has taught your brain that bed is a place for wakefulness and worry, not sleep. That is what we are addressing — not the original stress, which has gone, but the pattern your brain learned during that period."

💬 Why sleeping tablets will not solve a 6-month problem

"Can't you just give me something stronger for longer?"
"The tablets work well for the first few nights — there is no question about that. But here is what happens over weeks: your brain adapts to them. After 2–4 weeks they become less effective, and if you stop them suddenly the sleep gets worse temporarily — what we call rebound insomnia. That temporary worsening then confirms to you that you need the tablets, and a cycle begins that is very hard to get out of. The reason I am recommending CBT-I instead is that it targets the actual pattern that is maintaining your insomnia — and its effects last. Studies comparing CBT-I and sleeping tablets show that at 6 months and 12 months, the people who did CBT-I are sleeping significantly better than those who used tablets."

A — Chronic Insomnia Disorder
Primary diagnosis
ICSD-3/DSM-5: sleep difficulty (onset/maintenance/EMA) ≥3 nights/week; ≥3 months; daytime functional impairment; not better explained by another disorder; adequate sleep opportunity. Subtype here: mixed (onset + maintenance) with identified perpetuating factors (alcohol, compensatory behaviours, dysfunctional beliefs, conditioned arousal).
B — Exclude / Manage Concurrently
Screen at every consultation

OSA

STOP-BANG ≥3: refer for home sleep study; no hypnotics.

Depression (EMW)

PHQ-9; antidepressant choice drives management.

PTSD / RLS / Thyroid

Each requires specific management distinct from CBT-I alone.

C — The 3P Framework
Predisposing · Precipitating · Perpetuating
Predisposing: Female; perfectionist; anxious temperament; FH insomnia
Precipitating: Work inspection stress (resolved)
Perpetuating: Conditioned arousal; alcohol as sleep aid; extended time in bed; dysfunctional sleep beliefs; zopiclone use escalation
Treatment targets the perpetuating factors — not the original stressor
🎓 SCA Checkpoint — Step 5TasksRelating to Others
Explaining the diagnosis
"What has happened is that the original stress — the inspection — has gone. But during those months, your brain learned some new habits about sleep. Bed has become associated with lying awake, watching the clock, and worrying. The good news is: that pattern can be unlearned."

  • Not explaining why the insomnia persists after the trigger resolved
  • Not explaining why tablets alone will not solve it
  • Framing insomnia as untreatable or requiring indefinite medication

Step 6
Referral — When, Where, and What to Include
collapse
Most insomnia is managed entirely in primary care. CBT-I is available via NHS Talking Therapies (free; self-referral or GP referral), digital CBT-I apps (Sleepio — NICE-recommended; evidence-based), and face-to-face CBT in secondary care for complex or refractory cases. OSA referral is the most urgent from the insomnia differential diagnosis. Specialist sleep medicine is reserved for complex presentations.
ReferralUrgencyWhat to includeWhat NOT to do
NHS Talking Therapies — CBT-I (primary care psychological therapies)Routine (can self-refer)Chronic insomnia ≥3 months; perpetuating factors identified; sleep diary results; STOP-BANG negative; OSA excluded; PHQ-9 and GAD-7 scores. CBT-I typically 6–8 sessions; digital CBT-I (Sleepio) as first option if patient prefers self-directed approach.Do NOT refer to NHS Talking Therapies as a substitute for a GP discussion — the CBT-I rationale should be introduced at the GP consultation; NHS Talking Therapies delivers the treatment. Do NOT refer if OSA has not been excluded.
Respiratory medicine / Sleep medicine — OSA4 weeks (or urgent if severe)STOP-BANG score; ESS score; snoring history; witnessed apnoeas; BMI; neck circumference; airway assessment; BP; current medications. No hypnotics prescribed pending referral — document reason.Do NOT prescribe hypnotics while awaiting OSA assessment — risk of respiratory depression. Do NOT accept patient self-report of "normal" snoring without STOP-BANG assessment.
Specialist sleep medicine — complex / refractory insomniaRoutineInsomnia refractory to CBT-I; possible RLS or PLMD; narcolepsy features; complex psychiatric comorbidity; polysomnography indicated. Include sleep diary, PHQ-9, GAD-7, STOP-BANG, medication list.Not needed for primary chronic insomnia responding to CBT-I. Reserve for cases where CBT-I has been tried and failed, or where the diagnosis is unclear.
Alcohol liaison / addiction servicesRoutine (urgent if dependent)AUDIT-C score; drinking pattern; relationship of alcohol to sleep; evidence of escalation; tolerance; withdrawal symptoms on abstinence. Brief intervention first for hazardous use; structured alcohol treatment for dependence.Do NOT advise abrupt alcohol cessation in a dependent patient — risk of withdrawal seizures. Medically supervised alcohol withdrawal if dependent.

7A — Expectations and the CBT-I conversation
🤝
Addressing the sleeping tablet expectation without dismissing the patient — three steps
1
Validate — the expectation is legitimate

The patient has been suffering for 6 months, has tried what she knows, and knows from experience that zopiclone provides short-term relief. Validating this experience before explaining its limitations maintains the therapeutic relationship and makes the patient receptive to an alternative.

"I understand why you are asking — zopiclone clearly helped in the past, and 6 months of poor sleep is genuinely affecting your life in real ways. That is a completely reasonable place to be."
2
Explain — why a longer course will not work

The clinical explanation of tolerance, dependence, and rebound insomnia is the key educational intervention of this consultation. It should be delivered without judgment and with evidence.

"The issue with sleeping tablets for a problem of this duration is that your brain adapts to them — usually within 2–4 weeks — and then they become much less effective. When you stop them, you get a brief period of worse sleep — rebound insomnia — which feels like the original problem has come back. This cycle is what I want to help you avoid."
3
Offer — CBT-I is more effective and available

CBT-I is not a suggestion to "just think positively." It is a structured, evidence-based therapeutic programme with RCT evidence showing it is more effective than hypnotics at 6 and 12 months. NICE NG215 (2022) positions it as first-line for chronic insomnia. It is available free via NHS Talking Therapies and digitally via Sleepio.

"There is a therapy called CBT-I — it is a structured 6–8-week programme that directly targets the patterns that are keeping your sleep problem going. The evidence shows that at 6 months, people who complete CBT-I sleep significantly better than those who used tablets. It is available free, and you can even start digitally."

Key messages for today
"CBT-I feels counterintuitive — it asks you to do things that seem to make the problem worse at first (less time in bed; getting out of bed when you cannot sleep). But the research evidence is clear: this approach works, and its effects are lasting."
"The alcohol is working against you in the second half of the night. Reducing it by one glass — especially on school nights — may make a noticeable difference to the 3am waking within days."
7C — CBT-I: the five core components
NICE NG215 (2022): CBT-I is recommended for all adults with chronic insomnia (≥3 months). It is more effective than hypnotics at 6 and 12 months. It works by targeting the perpetuating factors — conditioned arousal, dysfunctional sleep beliefs, and maladaptive sleep behaviours — rather than just promoting acute sleep. Effect size: comparable to methylphenidate for ADHD or antidepressants for depression.
Stimulus Control
Rebuilding bed = sleep association
Principle

The bed has become associated with wakefulness through repeated episodes of lying awake, worrying, and clock-watching. Stimulus control rebuilds the bed as a sleep-only stimulus by restricting its use to sleep and sex only, and introducing a "get up" rule: if not asleep within 20 minutes, get up, go to another room, do something calming, and return only when sleepy.

Instructions

Use bed only for sleep and sex. No reading, screens, or watching TV in bed. If awake >20 minutes: get up; do something calming (reading, gentle stretch); return when sleepy. Set a consistent wake time regardless of when you fell asleep. Avoid daytime naps.

Most effective single CBT-I component for conditioned arousal
📉
Sleep Restriction Therapy
Rebuilds homeostatic sleep drive
Principle

Deliberately reduce time in bed to match actual sleep time — typically 5–6 hours initially. This builds intense homeostatic sleep pressure, consolidates sleep, and rebuilds the association between going to bed and falling asleep rapidly. Counter-intuitive and initially makes sleepiness worse — but produces dramatic improvement in sleep quality within 2 weeks.

Instructions

Calculate average sleep time from sleep diary. Set time-in-bed to match this (minimum 5 hours). Maintain for 1–2 weeks. Once sleep efficiency >90%: extend time in bed by 15 minutes. Repeat until optimal duration achieved. Not recommended in bipolar disorder, seizure disorder, or safety-critical occupations during titration.

Strongest evidence base of all CBT-I components; dramatic results in 2 weeks
🧠
Cognitive Restructuring
Challenging dysfunctional sleep beliefs
Principle

Catastrophic beliefs about sleep ("I must get 8 hours or tomorrow will be terrible"; "I have lost the ability to sleep") create anticipatory anxiety that increases arousal at bedtime. Cognitive restructuring identifies these beliefs and replaces them with accurate, proportionate alternatives. Key tool: sleep facts (most adults need 7–9 hours; short-term insomnia does not cause lasting harm; sleep quality matters more than quantity).

Example reframes

"I must get 8 hours" → "Research shows most adults function well on 6.5–8 hours; the specific number matters less than the quality." "One bad night ruins the day" → "We are much more resilient to sleep loss than we feel; most 'insomnia days' are better than expected."

Targets the anxiety about sleep that perpetuates the problem
🌙
Sleep Hygiene (Targeted)
Not generic — address specific perpetuating factors
Evidence

Generic sleep hygiene advice alone (leaflets, website links) is no more effective than placebo for chronic insomnia. However, targeted sleep hygiene that directly addresses identified perpetuating factors has a meaningful role within CBT-I. Key targets for Priya: alcohol reduction (explain the 3am waking mechanism); consistent wake time; no clock-watching; avoiding blue light 1h before bed.

The 3am waking and alcohol

Alcohol: sedating in first half of night (helps sleep onset); as alcohol is metabolised (2–4h), rebound arousal in the second half. REM suppression: first REM cycle is suppressed; rebound REM in second half = vivid dreams, restless sleep, early waking. Mechanism explained makes the recommendation compelling rather than lecturing.

Alcohol mechanism explanation is the highest-yield sleep hygiene intervention
🧘
Relaxation and Mindfulness
Reducing physiological arousal
Evidence

Relaxation training (progressive muscle relaxation, deep breathing) and mindfulness-based approaches (MBSR for insomnia; mindfulness-based CBT-I) reduce the physiological hyperarousal that prevents sleep onset. Most effective as a component of CBT-I rather than as a standalone treatment. Particularly useful for patients with prominent anxiety features or somatic arousal.

Practical

Progressive muscle relaxation: systematically tense and release muscle groups, 15–20 minutes before sleep. Breathing: 4-7-8 breathing technique. Mindfulness: body scan meditation (free via Headspace, Calm, or Insight Timer). NOT "try harder to relax" — paradoxical relaxation is a specific technique.

Reduces physiological hyperarousal — component of full CBT-I programme
📱
Digital CBT-I (Sleepio)
NICE-recommended; accessible; evidence-based
Evidence

Sleepio: RCT evidence; NICE NG215-recommended digital CBT-I programme. 6-week self-guided programme delivering all five CBT-I components via a personalised digital platform. Demonstrated effectiveness comparable to face-to-face CBT-I in RCTs. Available 24/7; suitable for patients who prefer digital self-directed approach or where NHS Talking Therapies waiting times are long.

Practical

Prescribe or recommend Sleepio via GP or self-access. NHS access in some areas free via ICB contracts. Sleep diary built in. Weekly sessions. Requires motivation and commitment — brief interview at first GP consultation to confirm patient is willing to engage. Patients who complete all 6 sessions have the best outcomes.

NICE NG215-recommended; RCT evidence; accessible
7D — Hypnotics: when, which, and for how long
NICE NG215 (2022): hypnotics are not recommended as routine first-line treatment for chronic insomnia. They may have a limited role in acute severe insomnia or as a short-term bridge while CBT-I is initiated. Maximum duration 4 weeks. Z-drugs (zopiclone, zolpidem) have the same mechanism and dependence risk as benzodiazepines. Avoid in elderly (fall risk, cognitive impairment). Melatonin (Circadin) is the safest option in ≥55 years for short-term use.
When a short-term hypnotic may be appropriate
  • Acute severe insomnia (<3 months) causing significant functional impairment — brief course while initiating sleep hygiene and CBT-I referral
  • Short-term use for specific trigger (bereavement, hospitalisation, travel) — 3–7 nights maximum
  • Bridge while waiting for CBT-I to take effect — acknowledging this is not the long-term solution
  • Never as sole treatment without concurrent CBT-I referral — this is the key clinical principle
When hypnotics are contraindicated or inappropriate
  • OSA (confirmed or suspected) — absolute contraindication; respiratory depression risk
  • Chronic insomnia (>3 months) without concurrent CBT-I — tablets will not solve a chronic problem
  • Elderly patients — Z-drugs: fall risk, next-day sedation, cognitive impairment; use Circadin 2mg MR instead if medication needed
  • History of dependence on alcohol, benzodiazepines, or Z-drugs — high re-dependence risk
  • Pregnancy — avoid
7E — Medication selector

Select patient characteristics — see drug cards below

Medication selection guide
Chronic insomnia: CBT-I first-line (NICE NG215) — NHS Talking Therapies or Sleepio. If short-term hypnotic needed: Zopiclone 3.75mg (age ≤65) or 7.5mg max; ≤4 weeks; review at 2 weeks. Age ≥55: Circadin 2mg MR is the safest option (no fall risk, no dependence). Depression + insomnia: Mirtazapine (sedating, 15–45mg nocte) or Sertraline (activating — give in morning). Z-drug dependence: gradual dose reduction over 4–12 weeks; CBT-I alongside. OSA suspected: STOP-BANG + ESS; home sleep study; NO hypnotics — respiratory depression risk.
7F — Drug reference cards
Zopiclone — Short-Term Only
Zopiclone 3.75mg / 7.5mg tablets · Z-drug · Caution: same dependence risk as benzodiazepines
⚠ Short-term only (≤4 weeks)
Not first-line; ≤4 weeks max3.75mg (elderly/renal/hepatic); 7.5mg standard
✓ When appropriate (limited)
Acute severe insomnia causing significant functional impairment; short-term bridge while CBT-I initiated; specific time-limited trigger (bereavement, hospitalisation). Always alongside CBT-I referral — never as sole treatment for chronic insomnia
✗ Avoid if
OSA (confirmed or suspected) — absolute contraindication; respiratory depression; potentially fatal. STOP-BANG ≥3: do NOT prescribe until OSA excluded.
Previous dependence on alcohol, benzodiazepines, or Z-drugs — high risk of dependence
Elderly (≥65): higher fall risk, cognitive impairment, next-day sedation — use Circadin 2mg MR instead; halve dose to 3.75mg if zopiclone unavoidable
Chronic insomnia (>3 months) without concurrent CBT-I — will not address perpetuating factors; dependence risk outweighs benefit
⚠ Side effects
Bitter taste (metallic: distinctive Z-drug side effect). Next-day sedation (driving hazard). Anterograde amnesia (especially with alcohol). Tolerance within 2–4 weeks. Rebound insomnia on stopping. Falls in elderly. Complex sleep behaviours (sleepwalking, sleep-eating) — rare but documented.
🔬 Monitor
Review at 2 weeks: is CBT-I underway? Is dependence forming? Is dose being escalated? Aim to stop at 4 weeks — plan the stopping date at the time of prescribing. Document: no OSA; ≤4-week course agreed; CBT-I arranged.
💬 Counselling

"This tablet will help you sleep in the short term, but it is not a long-term solution — your brain adapts to it within 2–4 weeks and it becomes less effective. We will review in 2 weeks. Please do not take it with alcohol — the combination significantly increases the risk of respiratory depression and accidents. Do not drive the following morning if you feel drowsy."

NICE NG215: Z-drugs are NOT first-line for chronic insomnia. Prescribing zopiclone as the primary response to a 6-month insomnia without CBT-I discussion is a clinical error. OSA is an absolute contraindication — STOP-BANG before prescribing. Document: course length agreed (≤4 weeks); CBT-I arranged; no OSA features; driving advice given.

Melatonin MR (Circadin) — Age ≥55
Circadin 2mg MR tablets · Licensed: short-term primary insomnia age ≥55 · Safest hypnotic in elderly
✓ Preferred in elderly (≥55)
Safest option ≥55; no dependence; no falls2mg ON 1–2h before bed; max 3 months licensed
✓ Prefer when
Age ≥55 requiring pharmacological sleep support — Circadin has no dependence potential, no fall risk, and no next-day cognitive impairment; significantly safer than Z-drugs in this age group
Licensed for primary insomnia in adults ≥55 for up to 13 weeks (short-term)
Useful for circadian rhythm disruption (jet lag, shift work) in older adults alongside sleep hygiene measures
✗ Cautions
Evidence significantly weaker than Z-drugs for short-term sleep induction — manages expectations: "this will help your brain recognise when it is time to sleep; it is not as powerfully sedating as sleeping tablets, but it is much safer for you long-term"
Interactions: fluvoxamine increases melatonin levels significantly (reduce dose); warfarin — some evidence of interaction; monitor INR
⚠ Side effects
Generally very well tolerated. Headache. Dizziness. Nausea. Daytime drowsiness if dose too large or taken too close to waking time. No significant tolerance, dependence, or rebound insomnia on stopping.
🔬 Monitor
Review at 4–6 weeks: effective? Sleep diary comparison. CBT-I alongside at all ages — melatonin is an adjunct, not a substitute for sleep behavioural interventions. Annual cessation trial in long-term users.
💬 Counselling

"Take this 1–2 hours before you want to fall asleep — it works by signalling to your brain that it is nighttime. It is much gentler than sleeping tablets and does not cause dependence or drowsiness the following morning. It works best alongside a consistent bedtime routine."

Circadin 2mg MR is the preferred pharmacological option for insomnia in patients aged ≥55. No fall risk, no dependence, no next-day cognitive impairment — in contrast to Z-drugs which are associated with all three in elderly patients. Evidence is weaker for acute sleep induction than zopiclone — manage expectations while being clear about the safety advantage.

Mirtazapine — Depression + Insomnia
Mirtazapine 15mg / 30mg / 45mg tablets · Sedating antidepressant · Nocte administration
✓ Depression + insomnia
Depression comorbid; nocte; sedating15mg nocte; up to 30–45mg; titrate weekly
✓ Prefer when
Depression confirmed (PHQ-9 ≥10) alongside insomnia — mirtazapine addresses both depression and sleep simultaneously; sedating antihistaminergic properties improve sleep onset and maintenance
Patient specifically requests a "tablet that helps sleep" in context of confirmed depression — mirtazapine is the antidepressant that most directly addresses the sleep complaint
Counter-intuitively: mirtazapine is more sedating at 15mg than 30mg (antihistamine effect dominant at lower doses); start at 15mg and titrate up for antidepressant effect
✗ Avoid if
No confirmed depression — mirtazapine should not be prescribed as a hypnotic for primary insomnia without depression
Weight gain is significant and persistent — discuss with patient, particularly if BMI already elevated. Appetite stimulation (particularly carbohydrate craving) is a common and distressing side effect.
⚠ Side effects
Sedation (therapeutic in depression + insomnia; dose it at night). Significant weight gain and appetite increase. Dry mouth. Agranulocytosis (rare; if fever or sore throat: FBC urgently). QTc prolongation at high doses.
🔬 Monitor
Weight at 4 and 12 weeks. PHQ-9 at 2, 4, 8, 12 weeks. Suicidal ideation in first 2 weeks (black-box warning). Sleep: direct monitoring — has the insomnia improved alongside the depression?
💬 Counselling

"This tablet treats both the low mood and the sleep problem together — take it at night, 30 minutes before bed. The sleepiness it causes is actually beneficial for you at night-time. It is likely to make you feel hungrier and you may gain weight — please tell us if this becomes a significant problem."

Mirtazapine is the antidepressant of choice when both depression and insomnia are present — it addresses both directly. More sedating at 15mg than 30mg (counterintuitive: antihistamine effect dominates at low doses). Weight gain is significant — discuss before prescribing. Do NOT prescribe as a hypnotic for primary insomnia without depression.

Sertraline — Depression with Insomnia (Morning Dosing)
Sertraline 50mg / 100mg tablets · SSRI · Activating — morning dosing essential
✓ Depression; morning dose critical
Depression; activating — morning only50mg OD in morning; up to 200mg
✓ When appropriate
Depression where sertraline is preferred (fewer interactions than mirtazapine; better tolerated in certain patients; sexual side effects less prominent than fluoxetine)
MUST be taken in the morning — sertraline is activating; evening dosing significantly worsens insomnia. This is one of the most common GP prescribing errors in depression with insomnia.
✗ Key issue in insomnia
Evening dosing causes or worsens insomnia — if a patient with depression and insomnia is taking sertraline at night, change to morning dosing before adding a hypnotic
⚠ Side effects
Nausea (with food), initial anxiety increase (first 1–2 weeks — warn patient), insomnia (if evening dosing — always give in morning), sexual dysfunction, headache.
🔬 Monitor
PHQ-9 at 2, 4, 8, 12 weeks. Sleep specifically — did morning dosing change improve sleep? Suicidal ideation in first 2 weeks (black-box in under 25s). Ask about sexual side effects at 4-week review.
💬 Counselling

"Take this in the morning with breakfast — this is important because this tablet is energising and can disrupt sleep if taken in the evening. It may take 4–6 weeks to feel the full antidepressant effect. In the first 1–2 weeks you may feel slightly more anxious — this is temporary and will settle."

High-yield SCA distinction: sertraline is activating — it must be given in the morning in any patient with insomnia. Evening sertraline dosing causing or worsening insomnia is a very common GP prescribing error. If a patient is taking sertraline at night and sleeping poorly — change the timing before adding a hypnotic. This often resolves the insomnia without additional medication.

Zopiclone Deprescribing — Gradual Dose Reduction
Zopiclone 7.5mg → 3.75mg → alternate nights → stop · Typical taper 4–12 weeks
✓ Dependence management
Dependence; taper plan; CBT-I alongsideReduce by 25–50% every 1–2 weeks; slower if significant dependence
✓ Deprescribing principles
Gradual dose reduction over 4–12 weeks prevents withdrawal symptoms (anxiety, irritability, rebound insomnia, tremor, seizures in severe benzodiazepine/Z-drug dependence)
Taper schedule: 7.5mg nightly → 7.5mg alternate nights + 3.75mg alternating → 3.75mg nightly → 3.75mg alternate nights → stop. Rate depends on duration of use and degree of dependence.
CBT-I must be initiated alongside the taper — the patient needs an effective alternative sleep strategy for when the tablets are stopped
Warn about rebound insomnia during taper — "temporary worsening is expected and is not a relapse; it lasts 1–2 weeks and then resolves"
✗ Do not stop abruptly
Abrupt Z-drug cessation after long-term use: withdrawal syndrome — anxiety, sweating, tremor, rebound insomnia; rarely seizures (more common with high-dose benzodiazepine dependence)
⚠ Expect during taper
Rebound insomnia (worse than baseline sleep for 1–2 weeks) — expected and temporary. Anxiety and irritability — temporary. Sleep gradually improves as CBT-I takes effect. Melatonin (Circadin) may bridge the gap in patients ≥55.
🔬 Monitor
Weekly during active taper: withdrawal symptoms; sleep quality; CBT-I engagement. Once stable on reduced dose: 2–4-weekly. Post-taper: follow-up at 4 weeks to confirm sleep maintaining without medication.
💬 Counselling

"We are going to reduce the tablets very slowly — slowly enough that your body adjusts at each step. During the process, you will almost certainly have some nights that are worse than usual. This is expected and temporary — it is called rebound insomnia, and it settles within 1–2 weeks at each step. It is not a sign that you will always need tablets."

Zopiclone deprescribing: graduated taper over 4–12 weeks; CBT-I mandatory alongside; warn about rebound insomnia (temporary; does not mean relapse). Never stop abruptly after long-term use. Document the taper plan explicitly in the clinical record. Melatonin for patients ≥55 as a safer bridge during the taper.

Amitriptyline/trazodone: QTc prolongation — ECG before starting if cardiac history; avoid with other QTc-prolonging drugs. Amitriptyline: anticholinergic effects in elderly (confusion, urinary retention, falls). OSA: worsens upper airway tone.
⚠ Side effects
Anticholinergic (dry mouth, urinary retention, constipation, blurred vision). Next-day sedation (driving hazard). QTc prolongation (amitriptyline, trazodone). Orthostatic hypotension (falls in elderly).
🔬 Monitor
ECG before TCA if cardiac history. Sleep diary. Review at 4 weeks. Not for long-term use without reassessment. Falls assessment in elderly before prescribing any sedating agent.
💬 Counselling

"This is being used at a very low dose specifically to help with sleep — it is not an antidepressant dose. It may cause some dry mouth or morning grogginess. Please do not drive if you feel drowsy the next morning. Let us know if it is not helping after 2–3 weeks."

Low-dose amitriptyline and trazodone are off-label for insomnia and used only when first-line options (CBT-I; Circadin; zopiclone short-term) have been tried or are contraindicated. QTc prolongation risk with amitriptyline/trazodone requires ECG if cardiac history. Not for routine GP initiation without specialist input for complex refractory insomnia.

7G — Psychosocial impact
🫂
Chronic insomnia — the hidden occupational and relationship burden
Chronic insomnia is consistently underestimated in its functional consequences. The patient who has not slept well for 6 months is operating with significantly impaired concentration, working memory, emotional regulation, and decision-making — equivalent in cognitive terms to moderate alcohol intoxication during the day. This impacts their professional performance, their relationships, and their sense of identity. Naming this specifically is both therapeutically important and motivationally powerful for CBT-I engagement.
💼
Occupational Consequences

Teaching with chronic sleep deprivation is cognitively demanding. Priya's concentration difficulties, irritability, and fatigue directly impair her professional performance — creating a secondary anxiety about work performance that itself maintains the hyperarousal at night. The occupational consequences are both a consequence of and a perpetuating factor for the insomnia.

"You mentioned the insomnia is affecting your teaching. The concentration and irritability from chronic sleep deprivation are real and significant — they are as impairing as mild alcohol intoxication during the day. Treating the insomnia effectively will directly improve your performance at work."
💑
Relationship Impact

Chronic insomnia affects couples significantly: if one partner cannot sleep, both are affected. Sleep deprivation causes irritability, emotional dysregulation, and reduced empathy — all damaging to intimate relationships. The snoring (mentioned by Priya's husband) may be a secondary concern the couple has not raised directly — it may represent an unspoken worry about OSA or just the mutual impact of disrupted sleep.

"How is the sleep problem affecting your relationship with your husband? Poor sleep makes us more irritable and less patient — that is a direct neurological effect, not a character flaw. Has it put strain on things at home?"
🔄
The Metacognitive Cycle

The metacognitive cycle in insomnia: lying awake → worrying about not sleeping → monitoring sleep ("only 2 hours so far — I'll be exhausted tomorrow") → increased arousal → lying awake. This second-order problem (worry about sleep, not worry about external stressors) is the primary maintenance mechanism for chronic insomnia and the central target of CBT-I cognitive restructuring.

"Does it feel like the original worry — the inspection — has been replaced by a new worry, which is the sleep itself? As if now your brain is monitoring the sleep constantly, watching the clock, checking how much you have had?"
🍷
Alcohol — the Double-Edged Crutch

The patient who uses alcohol to manage sleep onset has developed a self-medication strategy that provides short-term relief (genuine sedation) at the cost of long-term disruption (second-half-of-night arousal, REM disruption). The risk is escalation: as tolerance develops, more alcohol is needed for the same sedating effect — creating a pattern that meets the criteria for alcohol use disorder without the patient recognising it as problematic.

"You mentioned the wine helps you wind down. I want to explore that a little further — not to lecture you, but because the way alcohol interacts with sleep is quite specific, and understanding it might actually help with the 3am waking."
🌡️
Health Anxiety About Sleep

The widespread media coverage of sleep deprivation's health consequences (dementia, cardiovascular disease, cancer, obesity, immune suppression) has created significant health anxiety in many insomnia patients. This anxiety is itself hyperarousing — it increases the stakes of every night of poor sleep, amplifying the conditioned arousal cycle. Providing accurate, proportionate information is therapeutic.

"I want to address the health worries directly — the evidence shows that chronic insomnia does increase health risks, but it is also a treatable condition. The damage from short-term insomnia is largely reversible with effective treatment. The anxiety about what the insomnia is doing to your health is itself part of what is maintaining it."
🔮
Prognosis

The prognosis for chronic insomnia with CBT-I is good: approximately 70–80% of patients who complete a full CBT-I programme report clinically significant improvement; 50% achieve full remission. The key prognostic factors: engagement with sleep restriction (the most uncomfortable component); consistency of the wake-time; and reduction of the perpetuating behaviours (alcohol, bed extension). Improvement is typically apparent within 2–3 weeks of starting sleep restriction.

"The research is genuinely encouraging: around 70–80% of people who complete the CBT-I programme report that their sleep significantly improves. The first 2 weeks can feel harder before it gets better — but most people see meaningful change within 3–4 weeks."

Any-Time Red Flags

Excessive daytime sleepiness worsening → urgent OSA investigation; DVLA advice. Mood deterioration → PHQ-9; antidepressant. Alcohol escalation → AUDIT-C; dependence screen; supervised withdrawal if dependent. Zopiclone dose escalation or obtaining from multiple sources → dependence; urgent deprescribing plan. Chest pain or arrhythmia on low-dose TCA → ECG; cardiology.

OSA: DVLA duty if EDS drivingAlcohol dependence: never stop abruptly
7I — Monitoring

Chronic insomnia monitoring framework

At every insomnia review: sleep diary (sleep efficiency, total sleep time, SOL, WASO); PHQ-9 and GAD-7 (depression and anxiety as perpetuating or comorbid conditions); alcohol (AUDIT-C if escalating); medication review (any hypnotics still in use? duration?); CBT-I progress (sessions completed; engagement); OSA symptoms (snoring, ESS — re-screen if symptoms change); DVLA (daytime sleepiness affecting driving — legal duty to advise notification).

7J — Safety-netting

⚠ Safety-nets for insomnia

🔴 Excessive daytime sleepiness and driving
"If you feel significantly drowsy during the day — particularly if you have ever felt at risk of falling asleep while driving — I have to advise you to inform the DVLA. I know that sounds alarming, but it is a legal requirement if sleep problems significantly impair your ability to drive safely. Please also avoid driving on any morning after taking zopiclone if you feel drowsy."
DVLA notification duty: ESS >15 or patient reports sleep-related near-accidents is a legal duty for the GP to advise. Document this conversation explicitly in the clinical record.
💊 Rebound insomnia when stopping Z-drug
"When you reduce or stop the zopiclone, expect 1–2 weeks of worse sleep than usual. This is called rebound insomnia — it is temporary and expected, not a sign the insomnia has come back permanently. If you push through this period using the CBT-I techniques, the sleep will settle and in many cases be better than it was on the tablets. Please contact us if the rebound is severe."
Rebound insomnia is the most common reason patients restart Z-drugs during a taper — pre-warning prevents this and reduces re-dependence.
🟠 Alcohol — what to do if it feels out of control
"You mentioned the wine most evenings helps you cope. I am not suggesting you stop completely immediately — but if you find yourself increasing the amount, or if you find you cannot have a night without it and feel unwell when you try, please come and see me. That is an important pattern that needs medical attention, and there is help available that is specifically designed for it."
Alcohol-dependent patients should not stop abruptly without medical supervision. Pre-warning the patient to return if alcohol feels out of control creates a therapeutic safety net without triggering immediate confrontation.

Closing the consultation
"The most effective treatment for insomnia of this duration is not sleeping tablets — it is a therapy called CBT-I. Studies show it works better than tablets at 6 months. I am going to refer you for that today."
"On the zopiclone — I understand it helped in the past. The issue is tolerance: within 2–4 weeks the brain adapts. For a 6-month problem, tablets will not solve it without addressing the underlying pattern. If we do use a short course, it will be alongside the CBT-I, not instead of it."
"The alcohol is working against you in the second half of the night. The 3am waking is a very specific pattern caused by alcohol metabolism — reducing by even one glass may make a real difference."
"I want to check your mood with a brief questionnaire, and I also want to make sure you know about the driving advice — if you ever feel sleepy enough to be unsafe at the wheel, please tell me and we will address that immediately."
"I'd like to see you in 2 weeks with the sleep diary and an update on whether you have been able to access the CBT-I. Is there anything else before we finish?"

"I need something to help me sleep. I've been struggling for 6 months now — it started during our school inspection, but the inspection is over and I still cannot sleep. I lie awake for hours, I wake at 3am and cannot get back to sleep, and I am exhausted all day. I have two glasses of wine most evenings to help me wind down — that does help me fall asleep but I keep waking up in the middle of the night."
Who you are

Priya Sharma, 44, secondary school biology teacher. Divorced 3 years ago (amicably); lives alone in a flat; grown daughter at university. School inspection 7 months ago — extremely stressful; she was the science department lead; the inspection went well but she found it acutely exhausting. Sleep problem began then; she assumed it would resolve after the inspection. It has not. She has not disclosed that she has been obtaining zopiclone online from a private prescription service (she will admit this if asked directly and non-judgmentally about all sleep aids she has tried).

Hidden agenda and concerns

Primary expectation: She wants a prescription for zopiclone or an equivalent. She has used it before (prescribed after her divorce) and found it helpful. She does not regard herself as dependent — she "chooses" when to take it. She is prepared for the GP to refuse and has pre-rehearsed arguments about why she needs it.

Hidden zopiclone use: She has bought zopiclone from a legitimate private online prescribing service (Zava/ZAVA or similar) three times in the last 5 months — approximately 28 tablets each time. She is using it 3–4 nights per week. She has not told anyone this because she feels slightly ashamed about it. If the GP asks non-judgmentally about "any other sleep aids, prescribed or obtained in other ways," she will disclose this honestly.

Concern about CBT-I: She is sceptical — "I don't see how talking about it will help me sleep." She responds positively if the GP explains the mechanism specifically (conditioned arousal; sleep restriction rebuilding sleep drive) rather than just saying "it's a therapy."

Alcohol: She has not connected the wine to the 3am waking and will be genuinely surprised by this explanation. She is receptive to changing her pattern if the mechanism makes sense to her. She does not drink more than 2 glasses and does not think she has a drinking problem.

Clinical details if asked
  • Sleep onset: 11pm to bed; awake until 1–1:30am if no zopiclone; midnight if wine + zopiclone. SOL 1–1.5h.
  • Night waking: consistently 3am; awake for 1–2 hours; cannot return to sleep; up at 5:30am for school
  • Total sleep: approximately 4–5 hours. Very tired in class, particularly after lunch.
  • Snoring: her husband mentioned it (ex-husband; she lives alone now; mentioned in passing). No witnessed apnoeas. No gasping. No morning headaches. No excessive daytime sleepiness severe enough for driving concern (ESS approximately 10–12).
  • Mood: PHQ-9 approximately 9 (mild depression; persistent low mood but not meeting moderate threshold; anhedonia mild; no suicidal ideation)
  • No RLS symptoms. No thyroid symptoms. No cardiac history. No pregnancy.
Reactions to key moments
  • When OSA is screened: "I do snore apparently — my ex mentioned it. But surely that is just snoring?" → remains uncertain; will accept referral for sleep study if GP explains clearly why it matters before prescribing.
  • When alcohol-3am link explained: "I had no idea that was what was causing the 3am waking. That is actually really interesting." → genuinely surprised; receptive to reducing. Will try reducing by one glass if the mechanism is explained.
  • When CBT-I mechanism explained: Initially sceptical. If GP explains "sleep restriction" specifically and the counterintuitive logic: "That sounds like it would make things worse at first — but I can see how it might work." Willing to try Sleepio if GP specifically recommends it.
  • When online zopiclone explored non-judgmentally: "I did get some online — I felt a bit embarrassed about that. Is that a problem?" → honest disclosure if asked without judgment.
  • Challenge line: "I understand about the therapy but can't you just give me something to help me sleep short-term while I wait? I can't keep teaching like this."
"I understand what you are saying about the therapy, but I am absolutely exhausted and I cannot keep functioning like this at work. Can't I just have a short course of sleeping tablets to get me through while I wait for the therapy to start? Surely a few weeks won't do any harm."

Resolution: Priya will be satisfied if the GP: (1) acknowledges the prescription request and her suffering before explaining an alternative; (2) explains the alcohol-3am waking mechanism clearly — this is the single most impactful clinical revelation for her; (3) explains CBT-I with a specific mechanism (not just "it's a talking therapy"); (4) explores the online zopiclone pattern without judgment; (5) screens for OSA and explains why before prescribing anything; (6) offers a limited short course of zopiclone (3.75–7.5mg, 2-week course) as a bridge IF STOP-BANG is low and OSA is not suspected — doing so alongside CBT-I is clinically appropriate in NICE NG215; (7) closes with a 2-week follow-up with sleep diary. She will disengage if she feels lectured about alcohol, judged about the online prescriptions, or given CBT-I as a dismissal rather than a recommendation.

🚦 1 — Triage Algorithm
Insomnia complaint → screen OSA (STOP-BANG) → PHQ-9 → perpetuating factors → 3P model → CBT-I first-line
🔴 Urgent
  • STOP-BANG ≥3 + EDS: sleep study; NO hypnotics
  • Alcohol dependence: supervised withdrawal
  • Narcolepsy (cataplexy): urgent sleep medicine
  • Suicidal ideation + insomnia: same-day mental health
OSA: absolute CI to hypnotics — respiratory depression
🟠 Weeks
  • Depression (EMW + PHQ-9 ≥10): mirtazapine nocte or sertraline AM
  • PTSD nightmares: Image Rehearsal Therapy; NHS Talking Therapies trauma pathway
  • Z-drug dependence: gradual taper; CBT-I alongside
Depression: mirtazapine nocte covers both
🟢 Routine
  • Chronic insomnia ≥3 months: CBT-I via NHS Talking Therapies or Sleepio
  • Short-term bridge: zopiclone ≤4 weeks alongside CBT-I
  • Age ≥55: Circadin 2mg MR (no dependence; no falls)
CBT-I: more effective than Z-drugs at 6 months
💊 2 — Drug Selection at a Glance
Drug by Scenario
Primary insomnia: CBT-I first. Short-term: Zopiclone 3.75–7.5mg ≤4 weeks (not OSA).
Age ≥55: Circadin 2mg MR ON (safer; no dependence; no falls).
Depression + insomnia: Mirtazapine 15mg nocte or Sertraline 50mg morning.
OSA: CPAP — absolutely NO hypnotics.
High-Yield Clinical Rules
Z-drugs = benzodiazepines: Same mechanism; same dependence risk; not safer
Elderly + Z-drug: Falls; cognitive impairment; use Circadin instead
Alcohol + 3am waking: Rebound arousal from metabolism; explain mechanism
Sertraline: Activating — must be morning dose; evening worsens insomnia
Mirtazapine: More sedating at 15mg than 30mg (antihistamine dominant)
Rebound insomnia: Temporary; 1–2 weeks; not relapse — warn before taper
CBT-I
NICE NG215 first-line for chronic insomnia — more effective than Z-drugs at 6 months
≤4 weeks
Maximum Z-drug duration; review at 2 weeks; never renew without reassessment
OSA = CI
Hypnotics are absolutely contraindicated in suspected or confirmed OSA — respiratory depression
STOP-BANG
Apply before every hypnotic prescription — failure to screen is a patient safety error
3am
3am waking = alcohol rebound OR depression (EMW) OR OSA — each needs different management
Circadin

💬 Key Phrases
💭 Acknowledge the expectation
"I understand you came in for a prescription — I am not dismissing that. Let me explain why for a problem of this duration I want to offer something more effective, not just something for tonight."
😟 Alcohol 3am mechanism
"The wine is genuinely sedating — it does help you fall asleep. The problem is in the second half of the night: as your body clears the alcohol, there is a rebound arousal. That is the 3am waking. Reducing it by one glass may be the single most effective change you can make."
🎯 CBT-I mechanism
"Your bed has become associated with lying awake and worrying because that is what has happened in it for 6 months. CBT-I re-establishes the bed as a sleep signal. The evidence shows it is more effective than tablets at 6 months."
🔬 Online prescriptions — non-judgmental
"I want to ask about any other sleep aids you have tried — prescribed, over-the-counter, or obtained in other ways. I am not going to judge — I just want to understand the full picture."
📋 Z-drug tolerance
"Zopiclone works well for the first few nights. But within 2–4 weeks your brain adapts, and it becomes much less effective. When you stop it, you typically have 1–2 weeks of worse sleep — rebound insomnia — which confirms to your brain that you need the tablets. That cycle is what I want to help you avoid."
💚 DVLA duty
"If you ever feel your daytime sleepiness is affecting your driving — that is something we need to address, and there is a legal requirement to notify the DVLA if driving is impaired. Please tell me if that becomes a concern."
🚫 8 Danger Zones
Zopiclone prescribed without CBT-I discussion→ NICE NG215: CBT-I is first-line for chronic insomnia. Prescribing zopiclone as the primary response to 6 months of insomnia — without discussing CBT-I — is a NICE violation and a missed therapeutic opportunity.
No OSA screen before hypnotic→ Zopiclone in undiagnosed OSA causes respiratory depression and is potentially fatal. STOP-BANG is a 30-second clinical screen. Failure to screen before prescribing is a patient safety error. Document STOP-BANG score in the prescription record.
Z-drug prescribed for >4 weeks without reassessment→ NICE NG215: hypnotics should not be prescribed for longer than 4 weeks. Chronic repeat prescriptions of zopiclone are a prescribing quality indicator failure. Review at 2 weeks; plan the stop date at the time of prescribing.
Alcohol not explored or mechanism not explained→ Alcohol-induced 3am waking is a perpetuating factor that can be modified. The mechanism explanation ("rebound arousal as alcohol is metabolised") is both accurate and motivating. Exploring alcohol without explaining the mechanism is an incomplete intervention.
Online prescriptions judged or not explored→ Online zopiclone access is a hidden pattern in many insomnia patients. Non-judgmental exploration reveals the extent of use and the dependence pattern. Judgment closes the conversation and prevents honest disclosure.
Depression missed (early morning waking + PHQ-9 not done)→ 3am early morning waking is a biological marker of depression. PHQ-9 must be done. Treating insomnia without treating underlying depression is inadequate management. Antidepressant choice matters: mirtazapine nocte addresses both.
Z-drug prescribed for elderly without considering Circadin→ Z-drugs in elderly patients cause falls, hip fractures, cognitive impairment, and next-day sedation. Circadin 2mg MR is licensed for age ≥55, has no fall risk, and no dependence. It should be first choice in elderly patients requiring pharmacological support for insomnia.
DVLA not mentioned when EDS affects driving→ GP legal duty to advise DVLA notification if excessive daytime sleepiness significantly impairs driving. Must be documented explicitly. ESS >15 or patient self-reports near-accidents: document "patient advised to inform DVLA per current guidance."
