narcolepsy
"This medication has changed my life.  I have never had a problem falling asleep.  But I wasn't experiencing restorative sleep.  I have been chronically fatigued my entire life.  This medicine has almost completely resolved my cataplexy.  I still have an occasional episode.  No stimulants ever helped.  I could take Ritalin, dexedrine and go right back to sleep.  I've never known what it felt like to get stage 4 restorative sleep.  It has helped my mood disorder and chronic pain as well.  Never underestimate the value of a good nights sleep.  This stuff has worked magic.  I don't know what will happen when the coupon expires as my insurance company has balked at paying the high price for this."
