I do, but Vyvanse gives me a strange anxiety every time I've tried it. More so than any ADHD stimulant I've tried. It's a shame because Vyvanse should be great on paper: the smoothness of dexedrine and the duration of Adderall XR with a more steady time release mechanism. For whatever reason it ends up being more anxiogenic and hyperthermic than Adderall. I'd really like to know why...
