Lisdexamfetamine
"Took for two months, 1 Capsule a day for my ADD. I have tried most ADHD medicines, stimulant and non- stimulant types. I was expecting a 'non event' transition, from adderall, to 

Dexedrine predominant Vyvanse. I have used Dexedrine and found it helpful with focus and follow through issues, with minimal side effects. Vyvanse did not turn out to be what I'd hoped for. Minimal fuss, and a stable continuation of living and treating my ADD. Vyvanse

Had no similarities to Dexedrine . Felt sad, bad, and disconnected from being in the moment.

Side effects did not disappear during course of treatment. Somehow a perfectly acceptable 

Drug ingredient, Dexedrine, became Lisdexamphetamine. The long acting formulation benefit is lost, to a imposter drug"
