One of my kids (1 of 2 with adhd) is on Strattera. He first tried ritalin, but that was really bad for him. Physically it was fine, but he ended up with a constant dark mood and dark thoughts that a 10 year old should not have.
He then tried Elvanse, and while it worked for his adhd, he seemed emotionally numbed. Unmedicated he was bouncing between the walls, but at least he was happy. On Elvanse he was just... numbed.
Now he's on Strattera, and he's not that bouncy anymore, and a much happier kid. And his parents aren't exhausted all the time either, which is a bonus. The only ill effects is that he sometimes gets a bit queazy for a short while after taking it, but it doesn't take long to pass. This could be a result of his aversion to pills, but bribing him with a glass of chocolate milk makes him take it without hesitation.
EDIT: For reference, his older brother had very good effect feom ritalin pretty much right away, so he's on concerta with reduced appetite as the only side effect. He eats like a T-rex in the eveneing to compensate, so it evens out with no issues.
