I take 50 mg. of Vyvanse every morning. It is pricey, but keeps me awake for up to 12 hrs. The only downside that I have is one out of four nights I may have trouble sleeping. But I've learned to relax my body and I'm OK the next day

This is a tough one since the effect of the medications seem to vary widely from person to person. For me Provigil has worked the best with minimal side effects. I have tried the following: Wakix, Xywav, Nuvigil. These three either didn't work well for me and/or gave me unacceptable side effects.

Thanks for replying!
