Ritalin
adhd
"I've been taking Ritalin (extended release) at 20mg for almost a year now. 

I take it for ADHD. (I also have bipolar disorder type I.) This medication

doesn't help with me when it comes to being hyper and full of energy all

the time, but it does help with concentration. The only side effect I have

experienced so far is loss of appetite, but not significantly."
