Antabuse was really great IME except it made me psychotic, but that's a rare side effect and it shouldn't have been given to me with my history of psychosis. Yeah you'll drink on it, but you're not going to repeat the experiment. And it takes about a week off it for the drug to clear enough to drink and not get ill. So a relapse needs to be planned in advance and you can always change your mind in that week and take it again. If it weren't for the antabuse psychosis, which again is rare, I would still be taking it.
