obstructive sleep apnea/hypopnea syndrome
"I was on Provigil for about 2 yrs, but when my doctor switched me to Nuvigil, it was so much better. I felt as if I had my life back and for months it worked. With both Provigil and Nuvigil, they work great for a while, then they seem to loose their power. I still have chronic fatigue, plus muscle weakness. I am hoping that my doctor will try me on something else."
