insomnia
"Well I have been on this drug since 2009.  I do not know I had an issue until I had a seizure after coming out of the shower.  I had all kinds of tests, and then went to a sleep lab.  There they said I never entered into REM.  So I was totally sleep deprived. I was put on .5mg and it did the trick.  I had the real dream and restless leg syndrome where my wife was scared of me.  I would yell kick and literally act my dream out and I would wake up exhausted.  Since 2009 I'm getting roughly 6 hr of sleep a night.  It is awesome.  Still have some nights, once a month depending on stress.  I travel internationally and my sleep schedule is messed up so I'm sure it doesn't help.  But it has worked for me thus far."
