I am 18, around 5'4", and weigh about 180 lbs. I do work and go to school so that keeps me busy, so I'm not a couch potatoe. I don't workout though, but am planning to start walking everyday. I have noticed that I've been eating more (I'm not pregnant either), and I would love to stop eating so much and lose 50 lbs, so I can be around 130 lbs like a "normal" woman! I have no health problems, besides being overweight. Should I go to my doctor for adipex? And would I have to quit drinking sodas?
