ADHD
"Works better than Concerta for ADHD-IA for attentiveness as well as alertness. Far superior to Concerta in regards to affecting sleep. Vyvanse doesn&#039;t keep you awake. Also seems to contrast greatly to Concerta&#039;s method of dealing with attentiveness. Makes a less &quot;zombie-like&quot; state of concentration and lets you break task when needed. An added effect is that of a more positive sense of well-being; most likely attributed to its amphetamine-based nature.

The greatest advantage is the delayed release into the body. Great for those whose metabolisms don&#039;t react well to Adderall XR or Concerta. Only wished it lasted about two hours longer in the body, but adapting dose time is acceptable."
