Victoria,
I have found myself in this position all too often. Thinking that it is a weekday and so of course I can manage just a beer or two as an after hours treat. Everyone else does, right? It just doesn't work for me either. I'm not sure I have come to accept that fact, it is sad to think that I can't just causally drink like others. But then, I don't see most others acting the way I do after a night out of "causal drinking." I'm sending strength your way.
