Campral didn't do jack for me. I had to get through it the hard way. But there is a new drug called naltrexone. I haven't taken it or know of anybody who has taken it, but I did read an article written by a Dr. who runs a rehab in Dallas. He stated that it prevents patients from becoming intoxicated and significantly reduces cravings. Given your husband's situation, it may be something you want to research and/or ask your physician about.
