adhd
"My 9 yr old son started vyvanse two weeks ago (lowest dosage) and we saw positive results right away.  In addition to ADHD he has a writing disorder and will literally sit and stare at his paper for hours because he can't get his thoughts written out.  The first day he tried vyvanse he took it in the morning and then came home from school and without being asked he finished his book (25 pages) and then sat down and wrote a 2.5 page book report!  I have not noticed a change in his appetite and he has only experienced some minor sleep issues but it does not seem to really bother him.  Testing has shown my son to be highly intelligent but his grades do not reflect that - I finally have hope that he can reach his potential!"
