I sleep a lot. Become exhausted very easy. My insurance would not cover my meds for migraine.. I contacted the actual company and they give it to me at zero cost

I was prescribed nuvigil (similar drug) I have to jump thru tons of hoops to get it but wouldn't survive without it. If I take it regularly it doesn't work as well as if I take it as needed for days I'm really needing it. I only take half a pill and have to take it before 9am or else I'm awake til 1am. Days I don't take it I'm asleep between 12-4 (uncontrollably ). I was out running errands once and got soooo tired I fell asleep at a stop light.
I hope you get the results you need.

Provigil did not work well for me but everyone is different. Do the prior auth and try it out. I now use low dose Ritalin.

I've taken Provigil off and on for years. My neuro started me on Amantadine but it did nothing for my fatigue and made me feel weird. I tried Provigil and never looked back. I take it now only as needed because I'm on lots of vitamins and supplements that help with my fatigue. Provigil allows me to be more alert and focused. It does tend to give me headaches though so when I do take it, I take a 200 mg ibuprofen chaser.
