I have been on Phentermine since February 2010 and I have only lost 12 pounds. At first the side effects were awful (not sleeping, nausea, appetite suppresant, energy) now they are almost non existent. I want to continue using this product but I have not hit my 10 pound weightloss goal in one month yet. I need help from someone in what I need to do to be successful with using this product and losing weight.
