Report an error or outdated claim.

Alcohol is a depressant that disrupts sleep, raises next-day anxiety and can reduce the benefit of antidepressants and therapy. Cannabis, stimulants and other substances have their own effects on mood, psychosis risk and sleep. UK guidance keeps weekly alcohol below 14 units spread across 3 or more days.

Honest questions

Is drinking being used to manage feelings rather than for enjoyment?
Does mood or anxiety reliably dip the day after drinking?
Has anyone close expressed concern?
Would two alcohol-free weeks be easy or hard?

Cutting down can improve mood within weeks. Dependence needs medical support, because stopping suddenly after heavy daily use can be dangerous. Drinkline on 0300 123 1110 (weekdays 9am to 8pm, weekends 11am to 4pm) and the GP are starting points.

If you or someone else cannot stay safe, call 999. Samaritans: 116 123, free, 24 hours.
