You are definately right about the diet and exercise, however; Lipozene is sold in stores now. In fact you can purchase it at Walmart for $19.99. I am taking the supplement now and I have not experienced any jitters, pain, or nervousness. It simply curbs my appetite. I take two pills daily and I do not get any hunger cravings through out the day. In fact, the urge to eat is so low that I have to "remember" eat the necessary amount of food in order to maintain a metabolism (b/c I have hypothyroidsm-underactive thyroid) and I feel fine. I have not taken the pills long enough to see any real weight-loss, but I will keep posting as I go.
