Concerta
"My 11 yo has been on concerta for 2 months. The first few days he did experience some nausea although went away. After the first week I could tell a huge difference in his attitude.. He suddenly had a sense of humor, engaged in conversation without being distracted, and was bringing home/completing homework with no trouble! His grades have immensely improved!! I can tell a difference (not huge) on the weekend days he doesn't take it. Or if he didnt sleep well the night before and when it begins to wear off in the evening he tends to be a little grouchy. Only other down side I've noticed so far is that he has lost approx 4lbs/mo which is concerning if it continues. So far, happy with the results!"
