We usually buy 3 gallons of milk a week....2 lowfats, and 1 nonfat. That's for a family of 4...I must say I drink the most though. I *love* milk. My mom sometimes makes cheese or yogurt out of one of the lowfat gallons, so we don't exactly *drink* all of it, but we do *use* all of it. My parents use milk in their tea too. I don't remember EVER throwing milk away. We end up throwing sodas allll the time....but never milk. I *have to* drink milk everyday, or my day is not complete. I usually drink one glass a day....sometimes 2. When I was younger, it had to be at least 3 glasses a day.
