Probably not the biggest, but I used to drink a lot, even in unnecessary situations, like having 2 king cans before going to a job interview.
I once skipped work for a week and went on a drinking binge. During that week I recall waking up at 9am, chugging like 4 beers, then decided to go to my friends house. I cut through an elementary school field, during recess, and started puking while a lot of kids were watching me. Some teacher even asked me if I was ok.
