Personally, I don't think that any kind of diet pills are really worth it. You have to diet and exercise with most of them, so most of the weight you've lost isn't from the pills. Plus the fact that it seems that after a pill has been around for awhile they find it has some ingrediant that can cause illness or even death in some cases. I'd rather just do some extra work on my part to lose the weight and avoid the risk, but to each their own.
Anyways, congrats on you weight loss and welcome to our board!
