In real life I only drink one or two beers a night during the week, sometimes abstaining completely. But I do tend to over do it during the weekends. It is easy to do when you have a nearly unlimited supply of beer. That said, recently I have been noticing that hangovers take way too long to recover from so I am starting to limit my intake on the weekend as well.
Of course, I just got back from a trip to Seattle visiting Tom Schmidlin where I pretty much tried to drink the entire town dry in 2.5 days. Tom brews some excellent beers, stop by Post Doc brewing if you are in the area!
