ADHD
"My son is now 13, and has been using Concerta the past 2 years. Was working great, went from doing homework until 12-1:00 am to finished before I got home from work.  Concentrated more and was overall happier with himself and his achievements. Around November he had started having trouble sleeping and eating and was acting different. I guess since he turned 13 and puberty is starting to set in it wasn&#039;t working for him anymore so we are changing medications. I do recommend this medicine though, while it worked, it was great."
