I tried pretty much every drug I heard of that was touted as an effective way to curb alcohol cravings - Campral, Naltrexone, Antabuse... Tried quite a few supplements, too, like Kudzu extract and St. John's Wort. Went through several therapists hoping that would help me stop drinking. Showed up to many of those sessions intoxicated. Read a fair amount of self help books, too. Some things I read were very thought-provoking and rang true, but addiction doesn't really care too much about reason.
At the end of the day, nothing was going to make me stop drinking until I hit rock bottom, at least for me, and whatever good effects I once got from alcohol were completely outweighed by a mountain of bad stuff. After 2 stints in rehab, I finally surrendered and went to AA. It has helped, and hasn't cost me a thing, other than what I feel compelled to give.
