Insomnia
Red Flags — do not manage as primary insomnia
| Red flag | Why important | Action |
|---|---|---|
| Snoring + witnessed apnoeas + excessive daytime sleepiness (STOP-BANG ≥3) | Obstructive sleep apnoea — the most dangerous missed diagnosis in insomnia. Hypnotics cause respiratory depression and can be fatal in severe OSA. CPAP is the treatment, not Z-drugs. | Home sleep study / polysomnography; respiratory / sleep medicine referral; no hypnotics |
| Early morning awakening + low mood + anhedonia + weight change | Biological depression — early morning awakening is a specific somatic marker of major depressive disorder. Treating the insomnia without treating the depression is inadequate. PHQ-9. | PHQ-9; antidepressant (mirtazapine — sedating; sertraline — activating, give in morning); CBT |
| Nightmares + hypervigilance + avoidance behaviour + trauma history | PTSD — nightmares and hypervigilance prevent restorative sleep; standard CBT-I is insufficient; trauma-focused CBT required. Image Rehearsal Therapy (IRT) is specific for PTSD nightmares. | PTSD assessment; trauma-focused CBT; Image Rehearsal Therapy; prazosin for nightmares (off-label) |
| Restless, crawling, uncomfortable sensation in legs at night relieved by movement | Restless legs syndrome (RLS) — a distinct sleep disorder requiring specific management (iron supplementation if ferritin <75; dopamine agonists). Standard sleep hygiene and hypnotics are ineffective. | Ferritin (supplement if <75 mcg/L); consider dopamine agonist (pramipexole) or gabapentinoids (specialist) |
| Prominent daytime sleepiness + cataplexy (sudden muscle weakness with emotion) | Narcolepsy — a distinct neurological sleep disorder. Cataplexy (laughter or surprise causing sudden weakness) is pathognomonic. Orexin (hypocretin) deficiency. Urgently refer to sleep medicine. | Urgent sleep medicine referral; polysomnography + MSLT; sodium oxybate / modafinil (specialist) |
| Significant alcohol use as primary sleep aid (≥14 units/week or escalating) | Alcohol dependence — if patient is drinking heavily to sleep, abrupt cessation can cause alcohol withdrawal (seizures, delirium tremens). AUDIT-C; medically supervised alcohol withdrawal if dependent. CBT-I alongside alcohol reduction. | AUDIT-C; CAGE; alcohol dependence screen; medically supervised withdrawal if dependent |
😟 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."- Prescribing zopiclone without exploring perpetuating factors and CBT-I

"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."
"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."

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."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."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."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.
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.
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.
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.
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).
"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."
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.
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.
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.
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.
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.
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.
- 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
- 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

"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.
"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.
"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.
"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.
"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.
"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.
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."2 Weeks — Sleep Diary Review and CBT-I Engagement
Sleep diary completed? Sleep efficiency calculated? OSA result back? CBT-I started (NHS Talking Therapies / Sleepio)? Alcohol: any change to evening pattern and effect on 3am waking? PHQ-9 reviewed. If short-term zopiclone prescribed: review dependence, efficacy, plan to stop. DVLA: any excessive daytime sleepiness affecting driving — document advice given.
4–6 Weeks — CBT-I Progress Review
CBT-I: which sessions completed? Sleep restriction initiated? Stimulus control implemented? Alcohol pattern changed? Sleep diary progress: is sleep efficiency improving? Any depression emerging (PHQ-9)? If deprescribing Z-drug: taper on track? Rebound insomnia managed? Sleep: is it improving?
3 Months — Treatment Response Assessment
CBT-I completed? Sleep significantly improved? Residual perpetuating factors? Alcohol normalised? If Z-drug: fully stopped? Mood: depression now detectable that was masked by insomnia focus initially? If minimal response to CBT-I: specialist sleep medicine referral; review for OSA or RLS missed.
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.
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).

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."
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.
