naltrexone
I have been taking 50 mg/day of Revia and it seems pretty subtle. I never had a big problem with physical withdrawal and I think it was designed more for that than psychological cravings. It would probably be futile if you tried to continue to drink.I was intrigued that they measured chages in the mri's of subjects when it was being tested...and wonder how they can tell it was the meds or just the persons physical brain recovering from being sober?
