"Vyvanse is great.  It has a longer dosing window than Adderall XR (12 vs 8 hours for me) and a slightly improved side-effect profile.  As a longtime (~16 years) prescription stimulant user, for ADHD, I would recommend Vyvanse to any user that is currently unsatisfied with their ADHD management.  It is no silver bullet, but there are no silver bullets for ADHD.  It is incremental innovation in a great way. Vyvanse is the first real stimulant to reduce side effects without cutting efficacy."
