drinking 64 oz of skim milk over a seven day period is really not "too much" but i do not know if you have a weight issue or not if you are female or if you have any other medical issues. basically when you are thirsty. drink water but when you want a glass of skim milk just have it.
i go through a gal of milk (skim free) in a little over a week. my mom says i drink way too much milk. healthy or not?
