Armodafinil
"I have OSAH and for the couple of years before this medicine- I couldn't drive more than 1 hour, or focus at work - I would fall asleep - regardless of the amount of sleep I got at night.  My CPAP helped, but still dozed off during the day. Since Nuvigal things are better, but still have some sleepiness if I have a rough week of less than 8 hours of sleep at night. Insurance pays most, but THANK YOU to the manufacturer who helps cover a portion, or else it would be costly."
