obstructive sleep apnea/hypopnea syndrome
"My first day on Nuvigil. I have not had this much energy in years and I'm only in my late 30s. Only side effects I've noticed so far are some very mild nausea. Just enough to suppress my appetite which is actually a good side effect. Had a mild headache this afternoon a couple of hours after taking the pill but cannot say that it was a result of the medication."
