We are in the process of finding the right medication for my 7 year old son recently diagnosed with ADHD. We tried Focalin and it made him very withdrawn and somewhat depressed. We are about to start Vyvanse so we'll see how that works. I'm very concerned about how these drugs affect a child's personality and mood. It's a trade-off I guess. You want your kids to be happy, but if they're constantly in trouble in school and can't focus, that has to have an impact on long-term happiness, right? I have a friend whose 2 kids went on Concerta around the same age, and she said the only side effect they experienced was loss of appetite in the middle of the day. But she said it was like someone flipped a switch inside them and they were suddenly able to concentrate and excel in school. I'm praying for the same outcome. It kills me to see my funny, happy boy change into someone he is not. Anyone else experience minimal side effects like my friend?
