I drink from the two liter sometimes (trying to break myself of that habit) but not if I know someone else might plan on pouring a glass from it since that's just nasty to drink from the same thing without permission from the other person I consider those health fanatics on TV that think you'll catch something from everything to be something along the lines of an ingrown toenail on society for giving people more to panic about when they already have enough to deal with so its not like I've never drank after someone/let someone drink after me but a warnings always nice though, haha.
if im going to finish the carton, then i might. but usually if there is only little left, i mix it with water to get more of it. and no, i dont mix milk with water , its just that i dont really drink milk anymore.
