My opinion is that if you're asking how to work up the courage on how to walk into your first meeting, then there is obviously a good reason why you want to quit drinking. Just think about that reason and you shouldn't have any trouble. AA is a very welcoming and comforting environment. You need not worry about judgement from the members as many of them were once in the position you're currently in. I was apprehensive and reluctant to go to AA. I had many fears built up inside, felt that I didn't belong or that I wouldn't ve accepted. Now I'm a full fledged member and I welcome the newcomers and let them know they are in a safe place.
