Atomoxetine
"I have aspergers and ADD and started taking strattera when I was about 9 or 10. And in just two months I lost over 20 kg (44 pounds) I was so skinny but I didn't change because I had tried everything else and this was the smallest side effects I had so far. But after I quit just over a month ago (I'm 17 now) I realized that the medication had caused me to have severe depression for all my childhood, I'm really happy for the first time in forever. and the medication had made me more angry and restless than when not taking them."
