insomnia
"I have taken Lunesta 3mg for 4 yrs and haven't had any problems with it. No side effects, no funny tastes, I just pop it in my mouth with a big drink and wala!  I take it and in about 30 min I'm asleep and don't wake up until the next morning with no hang over feeling, no headaches or anything. I have tried them all, I used to go for days and days without sleep so when I tried this and it worked it was like a whole new world opened up. This may just work different on some people as I was reading, but in my case IT WORKED!"
