zenchaser, play the tape through. You know you can't drink one night and then stop. You know what will happen if you try. You know what to do.
"I will never drink again" can be a hard one -- it can come with some sadness and feelings of loss, so we want to believe there might be a day when we can moderate. But think about all you gain in sobriety. And seriously, moderation just doesn't work for us.
