My wife and I bought one of these on our way out of Target the other day. Sure it was expensive, but it was cold and we were thirsty. Having said that, I’d rather drink motor oil than ever have this stuff again. The drink is horribly sweet and nasty. I figure this stuff mostly helps you lose weight by destroying your appetite (as well as your desire to live).
