"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&#039;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 &quot;high&quot; .. 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."
