ADHD
"I have been taking Concerta for (ADHD) about 3 months now.  The effects have been both positive and negative.  I started off with 36 mg and my grades were increasing rapidly, and I was more focused, but I started to become more antisocial, angry, I didn&#039;t have an appetite, I had sleeping problems and depression.  Then about two weeks ago I switched to 54 mg due to lack of focus, and my stomach has been troubling me. I&#039;m having twitching problems, and I am hearing voices."
