A typical Friday night in the 70s would be 7 beers before I left the house, two or three pitchers at a bar, usually accompanied by shots of whiskey. Then on top of the alcohol, there was cocaine, speed, and weed.
I actually have no idea. I have been drunk maybe three times ever, and the most drunk I ever got was senior year of college. Roomie had friends over and I was making gin drinks for myself and the one friend of mine who came and after five or so, I lost count (they were strong, probably a double shot in each) and blacked out soon after. I woke up on my couch, sans pants, at 6am, and later I found ten dollars in my bed. Good times.
My wedding reception was an afternoon affair. I think I had 2-3 magnums of champagne there, a shot or two maybe. Then, at the after-party, I remember ordering 1 drink, then drinks kept appearing in front of me so I drank those, too, and it's all really just a blur after that. It was just the one time; if I have 5 drinks a year it's been a big year for me.
