obstructive sleep apnea/hypopnea syndrome
"I am a 32 year old male and this is my second day on Nuvigil. Although I feel more alert at the start of the day, later in the day when the medicine wears off, oh boy does it wear off. I'm also feeling more hyper, moody, and an overall wanting to scream type feeling. I'm going to give it a few more days."
