When I was younger I tried pretty much every OTC "diet aid" out there. There were times when I was able to lose some pretty substantial pounds but it always came back every bit as fast as it left. Resulting conclusion of my personal "research" -
You have to look at the fine print - It always says: "when used with a sensible diet and exercise program" and "results not typical" always follows the *amazing* success story. To be quite honest, I think what ever results you might get are going to be the same with just the "sensible diet and exercise program".
As for curbing your hunger? If you are eating enough of the right foods, and drinking enough water, you aren't going to be experiencing *real* hunger anyway. I don't think a pill can curb emotional or mindless eating.
You can get a pretty good pile of fresh fruit and veggies for what that bottle of pills is going to cost and it's a much more stable long term investment.
