About the meds.....I'm not an MD, but I've taken all of the alcohol medicines and want to share my experience with you.
Antabuse is a horrible medication. It's old-school. You'll become ill even if you have fish cooked in a white wine sauce, for example. It does not reduce cravings.
There are some new medications that are effective at reducing the craving for alcohol. Ask your doctor about Campral and Naltrexone. Studies show impressive results when they are taken together. They are non-addictive.
Campral and Naltrexone, when combined with a recovery program (like AA), are very effective.
Best of luck!
