insomnia
"I have to be in bed by 8 pm to get a full nights sleep for work early the next morning.  I've never been able to fall asleep that early on my own, but Lunesta has been awesome.  It does not make me sleepy, but 15 minutes after taking it I lay down and just go to sleep.  At first I found I would wake up 4 or 5 hours later, but my doctor recommended taking melatonin with Lunesta.  Doing this (I take the 10mg time release melatonin) I sleep all night, easily wake up with the alarm clock, have no bad taste in my mouth, and am not groggy at all.  I do not take it on nights where I do not have to get up early the next day."
