Hi there...i'm kinda new here, but not new to ADHD and the meds that go with it. My son was on adderall which controlled the adhd, but gave him horrid anger issues. So we switched to Vyvanse. It's pricey for us (50 bucks for 30 days) but it made him a completely new child! It's been a wonder drug for him and us. I haven't noticed any other side effects with it other than the loss of appetite, which we've had with any other drug.
Every kid's different so no guarantees....but we are super happy with it!!
