Well it is my understanding that cow's milk isn't all that good for you in the first place, the human body isn't really made to digest it, but it still does, for most people. I, on the other hand, cannot handle cows milk, and sadly for me, I don't projectile vomit it back up, it just causes me untold amounts of extreme pain, that can last either a few hours, or a couple of days, and does cause a form of regurgitation kinda like acid reflux, only what comes up is thick, white, and in small quantities..... my body is pretty good about keeping what it needs down, and disposing of the rest. Nah, I don't want cow's milk thank you, I'll drink the chocolate Silk.
