insomnia
"I've been using Lunesta for almost a week now and it's wonderful!  It puts me to sleep relatively quickly (20 minutes as opposed to the several hours it usually takes).  It keeps me asleep 8 hours, sometimes longer if I don't have to work in the morning.  There is a bit of a "nasty" taste in the mouth in the morning but it isn't that bad and goes away after breakfast and teeth brushing.  Also the first few days I was a little drowsy still after waking up probably because the medicine was still in effect and my body wasn't used to so much sleep at once.  Now I wake up energized and I would definitely recommend this medicine to others!  A little pricey though."
