insomnia
"I have been taking this medication for about a year.  It puts me to sleep every night about 15 minutes after I have taken it.  I do have dreams which I hadn't had in years, they are not bad nightmares, just dreams about my stresses of life.  I feel so much better now that I take it, I wake up feeling great and ready to jump into my workout programs and life.  Before Lunesta I was tired, groucy, hard to get along with, now that I am catching up on my lost sleep of many years I feel wonderful!"
