Phendimetrazine
"I have been on and off of phendimetrizine 35 mg for three years. The first 2 months I ever took them I lost 50 pounds. Until the past year I had a great experience with it... although I would yo-yo if I came off the pills and diet, they were extremely effective while doing it correctly. I would STRONGLY recommend never combining the pills with alcohol, too much caffeine, or cigarettes. The last year has actually driven me to be very hesitant to use the medicine. I am truly nervous of having a heart attack. I became very nervous, anxious, experienced high blood pressure, and heart palpitations. It's scary. Just be very careful because you will eventually think you need these pills to lose weight, and that is terrible. Be careful!"
