Lisdexamfetamine
"My 6 year old son was diagnosed with ADHD and started on Vyvanse 4 weeks ago. He has made HUGE strides in school.  His teachers and I are all very impressed with what this medication has done for him academically.  However, he has become an emotional wreck.  If he isn't on auto-pilot or mentally checked out, he is snapping and yelling at people at the drop of a hat.  He zones out, acts and appears to be "high" .. a shell of him himself.  It breaks my heart to see my fun loving, humorous vibrant little boy become a drone so that he can be successful at school.  He is on the lowest dose of 20mg."
