Not going to speak for everyone. Although I do think this applies to everyone on this board, but I know some won't accept that, so I'll just speak for myself...
There is no "moderation" drinking for me. As an addict, and an alcoholic, that's just a fact. My brain doesn't let me "just have a couple". That is what defines me as an addict. It is not a desire to want a drink. It is not a desire to want to drink more than a few. It is literally my brain chemistry telling me that I NEED to drink, and that I NEED to drink MORE. There is no cure for that. It's nothing to be ashamed of, it's just something to accept and be cognizant of.
