Amphetamine
"This is the only medication we've tried so far for my 11 year old son, but it works. His school work has done a 180 degree turn since we started on Dyanavel.  The only downside is the flavor, which he hates, but he's motivated do he takes it anyway. We haven't had any negative side effects other than reduced appetite I'm the first few months taking the medication.  He's back to raiding the fridge 24/7 now though."
