I am looking for a diet pill that works well. I want to drop lots of weight during the school year. I need to drop at least 40-50 pounds. Right now I'm 190

. I would exercise but I cant due to hip problems. Because of the hip problems, I am overweight. So what can I use that works well?
P.S. I guarantee someone will say "diet pills are bad if your under 18" well I don't care. My immune system is very strong and I have no allergies. If something was going to hurt me internally I would not take it. I have family in the medical field and I am getting an early start on medical books. I KNOW MY MEDICAL RISKS!
