m a 48-yr old female trying to find the correct treatment for ADD. Vyvanase was prescribed for me as an alternative to
Adderall XR, because when that was first prescribed, it didn't last long enough (20 mg) and Vyvanase is supposed to have a much longer, smoother effect. Vyvanasee is supposed to be "exactly the same molecule" as Adderall - after it is ingested and goes through your system (and therefore less likely to be abused). To me, it felt like a completely different drug.
