P.M.
My sister has used it and says it works, but stay close to the bathroom. I have bought it and have used it but forget to take it, so I would not be a good person to judge on losing wieght with it. But we I have taken it, I kept to their food guidelines, % of fat in meals, (I kept my old weightwatcher guidelines in mind) and did not have a problem with needing the bathroom. I suspect my sister still ate high fat content foods and that is why she had a different reaction.
