When I was younger I was prescribed adderal for ADD. I was pretty skinny, I had abs without working out or anything, but I don't remember my exact weight. But when I was taken off of it, I gained weight, but not very much, Im about average weight. I'm going to go to the doctors soon to get back on Adderal, so that I can focus in school and when I drive, and I know weight loss is an effect. Im not trying to lose weight, but how much weight will I most likely lose? Right now Im 16 years old, 6', 145lbs. Will I be unhealthily skinny or will it not really be much of a problem?
