How coincidental; I just counted up the trophy bottles in my apartment and did the math yesterday. Between me and my 3 other roommates...
We drank 34 liters in 19 weeks. (not counting beer)
...that's a collective (average) change in our BAC by 15.44% (enough to give 34 people alcohol poisoning, and on average enough to kill 17 people) // 8.9 gallons worth of milk // 8500% more, INDIVIDUALLY, than the average person consumes in Saudi Arabia // 59.8 pounds of liquor (assuming each bottle weighs roughly the same)
34 liters / 19 weeks (38 days, since we drink Friday / Saturday) = .89 liters each Fri / Sat night (1.78 liters between the four of us each weekend.
This means I drink .45 liters every weekend, or 450ml, so...roughly this over each weekend:

So, I will say I was drunk From 8pm Friday to 4 am Saturday, then 7pm Saturday to 4am Sunday. 17 hours / 168 hours = drunkenness for 10% of my week, 90% sober.
College; it's a magical place.
