Lisdexamfetamine
"My 6 yr old son started on an ADHD regimen about 8 months ago.  We started on Concerta, increased dosage 3 different times, and switched to Vyvanase.  We have increased it to 30 mg and it still is not working.  However, now the moodiness, extreme sadness, and impulsiveness is much worse while on Vyvanse.  I really am considering just dealing with the ADHD without medicinal help.  I feel sorry for the little guy.  This is not what I want him to be like."
