"I have been taking Ritalin for about a month now. It really helps me focus on things. But a downfall is, it is really hard to multi-task. I can only concentrate on one thing at a time, and that makes it very difficult for my school work. Also, I have had a huge loss in appetite. I am not hungry, EVER. During the month I have been on this medicine I have lost almost twenty pounds due to the fact that I never want to eat."
