alcohol dependence
"this drug literally saved my life. 
I had a routine where after work everyday I would go to the liquor store, get a 40oz and knock it back, before heading to the bar. I did this for years. When I finally hit a wall (it's a long story) I saw a few different healthcare professionals, one of whom was a psychiatrist and he prescribed me Antabuse. He explained it to me very well, and asked me if I would try it and I agreed.
The thing about it is, this drug forces you to change your habits. It gives you the time you need to think things through and make different decisions. While I was taking Antabuse I had to take the time and thought required to figure out other things to do with my time. It was a process. IT WORKED. Sober 9yrs."
