insomnia
"I've been taking 10 mg.  every night for over a year. I used to be a napper sleeping 2hrs on and 2 hrs. off, sometimes I would stay awake for 3 days at a time. I'm prescribed 10 mg. nightly, I sleep thru the night and feel rested the next day with no hangover effect. I do not take it if I feel I can sleep without it. I have never had an adverse reaction to it. This medication has changed my life."
