Vyvanse 50mg in the morning keeps me awake nicely for 13-14 hours and it's focus lasts for 8-9 hours.

When I wake up, I take the pill, go back to sleep (Which makes me go into REM dream sleep) so I dream a lot and then I feel a sort of rejuvenation of wakefulness and movement - Like I'm able to easily move.

Cuz I have sleep inertia and hypersomnia without it. I also have wake inertia (The longer I stay awake, the harder it is to fall asleep again) and insomnia.

Concerta 2x 36mg in the morning works too but it's not as good and doesn't last as long. Vyvanse is more of a clean feeling.

I tried Adderall 20mg in the morning but it didn't wake me up so I decided to take 2x 20mg and was still sleeping + it doesn't last as long as Vyvanse. It was the generic version of Adderall not brand name.

That's just my experience.
