The only diet pill that i have ever seen work is the Phentermine 37.5.  I have tried every diet med. over the counter, and i even asked the pharm. at walgreens if there was anything over the counter that works as well as phentermine , and she told me to not waste my time or money because none of them work. BUT, as soon as i stopped taking them i started gaining the weight back. You have to get these from a dr. though. But be careful!!!!  Some of them will rip you off to no end!  Thank god i finally found the only Dr. that didn't lie to me and charge an arm and a leg....  I still haven't changed my eating habits, shame on me!
