Hi nana, after being on the provigil for some time, it stopped working and the nausea and fatigue came back. My pdoc put me on a low dose of dexedrine. Dexedrine is an addictive med so you have to be careful with it, but it has really helped me. Now, I feel almost normal...with no nausea, fatigue or depression. I am not a pdoc so I can't really say if it would help you or not. It's just what I have tried.
