adhd
"I used concerta for my ADD and it worked pretty good.  It gave me a little boost and helped me concentrate better but it kind of just felt like I was on a controlled form of caffeine. The side effects were a lack of hunger, mood swings, and the crash was terrible. I felt tired and got in a terrible mood.  So it does help I'm not going to lie but I have since switched to another medicine because the side effects were too much for me."
