ADHD
" I have been using Concerta for many years. It has helped so much, but the only downside to it is it makes me lose weight. I went off of my meds for about three months and gained 50 pounds. This was because I had the habit of eating whatever I want whenever I want and not gain any weight. I was an A  student and as soon as I went off my meds I was getting Fs in all of my classes. I then went back on my meds and within three weeks of me being back on concerta, I lost all of the weight I had gained(because I had to make the habit of not eating so much within those three months), I raised some of my grades to As and some to Ds. I still passed 7th grade because of my circumstance.I have ADD, ADHD, and Cerebral Paulsey."
