Eszopiclone
"I've had lifelong insomnia. My dad will tell you stories about all the nights he sat up rocking me because I didn't sleep. I've tried every over the counter remedy from melatonin, to valerian root, to sleepy time tea, to benedryl, to calms forte... nothing works for longer than 3 days at most, and it still takes hours to fall asleep. I've tried prescription sleep aids, and Lunesta has been by far the most useless of them all. It doesn't make me even a little bit sleepy. It does, however, leave the most foul taste in my mouth. It tastes like I've been sucking on an old penny and chewing the white part of a grapefruit peel. And it doesn't go away with brushing or mouthwash, it's just in your saliva forever."
