“I just can’t switch my head off at night”

A request for sleeping tablets with a "racing head" and a pointed "I don’t want to get into the why" is a flag to explore the CAUSE, not to prescribe a hypnotic. Here the engine is gambling disorder with ~£40k of concealed debt hidden from a pregnant partner — a treatable addiction, not "stress" or a moral failing. Critically, gambling disorder carries a HIGH suicide risk, so once it surfaces an EXPLICIT suicide-risk assessment is mandatory (thoughts of being better off dead, the "life insurance" ideation, plan, intent, means) — he will not volunteer it. Respond with safety planning, crisis-service involvement proportionate to risk (NICE NG225: needs, not risk scores), and concrete signposting: specialist gambling support and self-exclusion (NICE NG248: group CBT first; NHS specialist gambling services, the National Gambling Support Network via the National Gambling Helpline, GamCare, GamStop), debt advice (StepChange/Citizens Advice), alcohol and partner support — all in a non-judgemental space that makes disclosure of a shameful secret possible, and that dismantles the catastrophic "they’re better off without me" belief. A sleeping-tablet script alone would miss a life-threatening situation; the win is uncovering it, assessing risk, and coordinating help with early follow-up.
