Hi MtnMagic,
Congratulations on your deciding to get medical help. I took campral for only a short period of time- I personally didn't notice a difference in cravings, but, everyone is different. I also was prescribed antibuse which was MUCH stronger and I didn't dare drink while I was on it-It can be very toxic if drinking with it. Unfortunately, I could just quit taking antibuse for a few days and drink again. Darn addictions! Ask your doc! I finally decided not to do any drugs and checked myself into inpatient treatment - ended up being the smartest decision I made. Am sober now with no cravings. Don't know about lactimal.
Best wishes in your sobriety!
