obstructive sleep apnea/hypopnea syndrome
"I have just started taking Nuvigil for a few days now. For the last few years I have been taking medicines to calm me down and ease my stress levels. I felt like I was a walking zombie most of the time when I was awake, but most of the time I just slept. I can't believe how amazing this medicine is, the cloudiness is gone I feel like Rip Van Winkle when he finally woke up. Wow!"
