I had a 250mg Antabuse 9 hours ago & another 250mg at 6 pm the previous evening. When can I drink?

I dont know the answer but clearly Antabuse is not for you if you want to continue to drink. Id find an AA meeting and get there ASAP.

I wouldn't touch a a drink for at least 2 weeks.. I came off it 3 weeks before my holiday then drank vodka and it hit me harder than ever before. The question is Why are we wanting a drink when we are on Antabuse to get us off the alcohol??

I would not even think about it for 5 days, I worked out over the years that one antabuse tablet lasts 4 days and if you do drink the reaction will be very nasty and you will wish you hadn't.
Best wishes
