Dexmethylphenidate
"My son was so hyper that he couldn't even sit still to eat.  I would like to respond to the person who questioned her thin 6 year old being put on this medicine.  My son was actually able to put on some weight as he was able to focus and finish his meals.  Within a year he was at a normal weight for his height.  My son's doctor was able to explain that people with ADD or ADHD do not abuse this drug because it has the opposite affect on them than people without the disorder."
