I've been drinking about a gallon of 2% milk every 2-3 days, subbing in whole sometimes. I make pretty poor diet choices overall, though, mostly related to portion control. Fortunately, I don't really show it (other than maybe some skin problems) but I'm sure it's doing terrible things for my health. I've been trying to make an effort to at least eat healthy things, but I still eat binge style for the most part. I rarely eat breakfast, my "breakfast" is usually junk food out of the vending machines at work.
