insomnia
"I was on a cross country flight and took ambien in hopes of sleeping through the ordeal. I have severe anxiety when it comes to flying and a (seemingly unattainable) dream of mine is to be able to board, pass out, wake up when we land. I took TWO ambien and was rewarded with some mild symptoms of intoxication, a headache, and a few weepy spells. 

I thought this medication would do what I needed but now I guess I officially know there's no way to snuff out my nerves."
