True friends will support you. They may be weird at first because it may make them re-evaluate their behavior. My best friend and I have both been "trouble drinkers" but lately I've really gone off the edge. I'm pretty sure she feels as long as she doesn't go "as far" as me than she's okay and if I'm not drinking, well then she's the one out of control. But blah blah, my point is there WILL be a transition (one I'm about to go through myself!) but that the good friends will stick around. Are you in NYC? If so there are SO many meetings AA, NA that have all types of people, i'm sure you could find a fit. In fact at a meeting I was at on Friday a really handsome well dressed guy had the same "club" thing--alcohol and coke.
Oh, and welcome by the way.
