"my 4th grade son began taking concerta 2 1/2 weeks ago. it has been the best decision i ever made. his teacher says he is a completely different child. his funny personality remains but he is on task, finishes all his homework in class, and actually tells other children to quite down. i lamented for many, many months about whether or not to have him begin a stimulant. it is obvious that it was the right decision. i make sure he eats a hearty breakfast. he knows he needs to push himself to eat something at lunch and drink plenty of fluids. he did tell me he felt &quot;prickles in his head&quot; for the first 2 days. his teacher reported he was a little tired for a couple days as well. he says his mind is more clear and &quot;not so jumbled&quot;. we&#039;re thrilled"
