I know a lady who has been trying to get sober for eight years. Goes to AA, does all the stuff they tell you to do in AA, but she always has a non-alcohol beer at events - even AA events.
She isn't able to hold on to her sobriety for more than a few months at a time.
I don't know if that is part of the reason or not, but why even drink the stuff? I mean, I did it for the buzz.
