Well.. I've done it for a week and a half... lost 5 lbs so far. The doc really wants me to continue.. I agree, it is a bit pricey (although I don't mind that too much, as long as I lose weight).. the shakes don't taste very good at all, but they do keep me full and I don't really struggle with thinking about food constantly(which may just be mentally blocking it since I spent so much on the darn shakes). I'm going to stay on it and see how I do.. Thanks for responding since no one else did, lol.
