I'm taking Antabuse currently. I'm also on meds for anxiety and depression. I can say that it's no panacea and you definitely should get a second opinion regarding the dosing and drinking pattern your doc recommended. For me it's helped break the cycle only. The cravings are still there and only the fear of being violently ill if I consume anything for up to two weeks after cessation is the primary benefit. As for the side effects if you don't drink, that's another story altogether. As mentioned before, something like Naltrexone might be helpful if you're looking down the medicinal route. Be sure to stay engaged here---a lot of these folks are very supportive!
All the best.
