Had a 3 day course of diazepam (plus naproxen and co-codamol) this week for a muscle spasm. I know absolutely no alcohol whilst taking diazepam but How long until I can drink? I'm going to a festival at the weekend -a family one with my children so won't be getting drunk - but was planning on a few glasses of wine. Can I have wine (last diazepam was wed night) over the weekend? Or will I need to stick to soft drinks? Dr Google is quite vague on the length of time I need to wait. Any GPs around who can advise?
