I drink a gallon of 2% chocolate milk between 4 and 6:30 PM every day. Perhaps chocolate makes it go down easier?
I didn't realize I was drinking a gallon a day until I got a miniature fridge in my room and was the only person drinking milk out of it. It's easy to drink a gallon of milk when you're drinking it 64 ounces at a time!
