Well, I didn't want to believe it, but it looks like it's true. DS is taking ADHD medicine, and he seems to have become a different child at school. When he comes home, though, after an hour or so, he is hyper, like I've never seen him. I'm willing to tolerate it for the sake of making school easier for him. Is this common? Does the ADHD medicine (time released) just store up all that energy until it wears off?
