Well, I've taken antabuse and I'm really surprised your doc doesn't seem to have given you information about it! In my antabuse treatment I was not allowed to medicate at home, in other words, I was not given any tablets.
I had to go to my outpatient addiction center to take a breath test first and was given the tablet there. I had to check in with a nurse every single time I took a tablet. Part of the program was also ongoing liver checks. The dosage of my antabuse was carefully monitored.
I never drank on antabuse. One of the reasons for the close monitoring was that if I did drink on it, I may have been considered a bad candidate for the treatment and it might not have been continued.
Please be careful with this drug...I would recommend that you try to find an outpatient program where your use of it is monitored and where you can use it in conjunction with other treatment methods such as therapy....
