There is a saying in AA (ain't in the BB, I don't think) that there is a better chance of your drinking buddies getting you drunk than there is for you to help them get sober.
I have been sober a while and sometimes call my best former drinking friend to go to lunch.
He knows that he can turn to me at any time for anything.
But I couldn't go around him for the first few years, because it played a head game with me.
