ADHD
"I switched to Mydayis from Vyvanse. The effects of Mydayis last longer than Vyvanse, but just as&mdash;in my experience&mdash;Vyvanse did not last fourteen hours, Mydayis&rsquo;s duration of action falls short of the sixteen hours as advertised by Shire. Nonetheless, I still hold Mydayis superior to Vyvanse and Adderall."
