DH & I both have longstanding alcohol addictions. I've gotten us to the point of not drinking during the week, but we both imbibe more than a few on the weekends. Like you I was much more worried about caving for a glass or 6 of merlot than I was worried about eating, though I have my PMS food cravings too.
Except for one slip, I've been fine, for 2 and a half weeks now. My slip occured this past long weekend, camping at a trailer park with a bunch of friends and family, ALL partying their faces off. Survived the jam around the campfire the first night, the dance the second night, but karoke night got me on Sunday. So I made a couple of Mojitos, with fresh lime juice, maple syrup instead of simple syrup, soda water, shot of rum instead of the cayenne pepper. ALMOST a Master-Cleanse lemonade right? WRONG!
My stomach reacted swiftly and violently to the second drink, felt like a white hot fist was twisting my innards. I chugged a pile of water and staggered (due to pain, not rum!) into bed. Prayed to God to make this awful pain go away, and I would never, EVER do that again while fasting. Someone was listening because it went away and I felt fine the next day. I definitely WILL NOT be doing that again!
So I strayed off the path, but I found it again real fast and will stick to it this time. You are a lot stronger than you think you are, and when you start to feel better and better, more alive each day, it will be very reinforcing for you. It has been for me. When I get off this cleanse I'm going to start supplementing with niacin (vitamin B3) as there is a growing body of evidence (google Dr. John Cleary's research) that alcoholism is caused by a deficiency of B vitamins, especially B3. I can't find the link I wanted right now but he has cured very addicted people to the point where they don't drink often, but CAN have 2-3 drinks socially (occasionally)and then STOP. But here is a link with some information about B3:
