Obstructive Sleep Apnea/Hypopnea Syndrome
"My sleep apnea doctor prescribed this for me as I still felt tired during the day.  This has been a miracle drug.  I have energy during the day, think clearly, and have noticed my memory recall is much better.  (I am 51)  The down side of this drug is that it is not covered by most insurance.  Too bad... because I feel so much better and alert with this medication."
