I have gained 45 pounds over the last 5 years. I have tried dieting and keep failing. I lost weight at first then gained it back plus a lot more. It is affecting my knees and back. I am so unhappy with how I look. My daughter lives in another state, her doctor gave her fastin and she is having great results. The doctor I have says no drug works and will not prescribe it. Trying to find a doctor who will help me. I am 5' 5" and weigh 166lbs. This is too much for my frame.
