Yah, but you also have to think that would 6.7 pints filled to the brim. Nearly impossible. I'd say its probably around 8-9 pints bar equilivant pints a day.
I'd like to second I'd be very overweight as well. I had to quit drinking during the week b/c I had gained so much weight drinking 3-4 12oz's a day.
So people's metabolism can handle... mine can not.. partly b/c I'm confined to my 8x10 cubicle from 8-5 everyday.
