Switching from Adderall to Vyvanse specifically because of sleep complaints: does that switch usually help?

It can help for some people, though it's not a guaranteed fix, since the underlying reason a specific person is having sleep complaints on Adderall matters more than the switch itself. Vyvanse's gradual prodrug conversion tends to produce a smoother onset and offset compared to Adderall's more immediate release profile, and for someone whose sleep trouble was tied to a sharper crash or rebound effect as Adderall wears off in the evening, that smoother offset can genuinely reduce the disruption. If the change is persistent, distressing, or affecting daily functioning, contact your provider through the FasTreat portal rather than changing medication on your own.

Switched specifically because of a rough evening crash on Adderall and it genuinely fixed that particular problem, no more of that irritable, wired-but-exhausted feeling right before bed. Sleep onset itself is about the same as before though, so it wasn't some dramatic overall fix, just resolved that one specific piece that was actually bothering me most. Would say get clear with yourself on which exact symptom you're hoping the switch fixes before expecting it to improve everything at once.
