Are you sure you aren't setting yourself up, preparing for your next drink?
Just think....to fit in with the guys at work, to avoid awkward situations with close friends, and to be welcomed back into the open arms of your family, all you have to do is start drinking again.
Are you involved with a group of people who know how to stay away from a drink? I think that would be a better plan than trying to resist urges to drink some wine.
Take care of yourself.
