Oh and the pondering thing, yes, ponder ponder away, i know hangover days suck like that, but, I really think it's helpful just to write an account of it IMMEDIATELY so that you capture all the emotions and false logic that led up to it. The emotional attachments you give to certain AV excuses is especially important I think. Anyway, what I do, is write down immediately all that I can while it's fresh, and then try to leave it completely for a day or two, just be done with it, knowing it's there for my scrutinization when I'm ready.
