Every one of us has to learn to be around drinkers Justin.
I don't think your problem is a lack of willpower - I mean, you keep drinking despite the many times you've had horrible detoxes. That's some pretty sturdy will there.
Maybe acceptance is the key here?
Acceptance that your life needs to change...acceptance that you anmd alcohol will always be a toxic mix, and acceptance that it's the first drink that does the damage, not the last?
