When I take 50mg Vyvanse at 8am (40 minutes to wake up), it lasts until 4-5pm. When I take 50mg at noon, it lasts until 8-9pm.

What if I take 30mg at 8am (An hour to wake up), then 30mg at noon if I have nothing to do in the morning. When I have something to do in the morning, I can take 2x 30mg at 8am?

I can't go to sleep at 9pm. I just can't. I need to sleep at 12am because 9pm-12am is my peak thought time. My thoughts are faster but I can't focus.

I want to wake up and enjoy the morning and being able to focus before 12am too =[

If I really have to sleep 12 hours a night, I think taking 60mg at noon would allow me to focus from 9pm-12am anyways so..

(Me sleeps too much)
