obstructive sleep apnea/hypopnea syndrome
"I just started taking Nuvigil. Today is day 2. Before Nuvigil I have been suffering for the past 3 years or so with marked fatigue.  First I decided I should do a sleep study. They discovered that I have sleep apnea and I stop breathing about 50 times an hour. I got the CPAP machine and used it every night for the past 3 months. It didn't make the difference I was hoping. So, I talked to my Dr again and since I have young children I didn't want a sleeping medication and so he prescribed Nuvigil. Its been a life changer. I have the energy I used to have when playing with the kids and taking them outside instead of laying on the couch everyday."
