I took it for awhile when it first came out and I lost 20lbs but a lot of that was just hard work and effort on my part I think... I don't know if it was the alli that helped or not. I also tried it again but just couldnt get as dedicated. I had no problems with it at all but I didnt over eat either. My mom was asking if i still took it because she seen on the news that it was bad for you... i think it can damage maybe the liver? not real sure but I stopped taking it after that.
