My mom is on Campral and she said it's working really well. It's supposed to get rid of 50% to 75% of the cravings. Obviously the addict still has to want to quit in order for it to work. It's the closest thing to a miracle drug. My mom said her doctor at rehab said that it doesn't effect the liver and has little to no side effects. She also told me that she heard they were trying to come up with a similar version for drug addicts. Good luck to you and your husband
