Hello all, i am 17 years old, my name is Brandon, I have been taking concerta for my ADHD since i was 6 years old, I take 35mg every day, over the past 2/3 years I have been slowly losing weight, sadly it has got to the point where I can see my ribs and my own heart beating... I've tried everything from taking protein shakes everyday, working out 2 and a half hours a day, eating controlled meals daily,  taking food supplement tablets... I've tried everything.. nothing seams to be working... I've gone to my GP and they told me to keep up what I'm already doing but nothing is changing... I'm still losing weight.. please someone help me and let me know what else I can do..? Please?
