Hi Rose,
After may failed attempts to stay on the wagon I went to see my Dr. He prescribed naltrexone and I've been taking it (50mg) daily for about two weeks now. My experience is that it helps a lot of my cravings, but its not a magic pill. You must have a support group and a strong desire to stay sober. It seems to be working for me. Minor side effect is very slight stomach cramps but not too bad and the longer I've been taking it the better it gets. Stay strong.
