Suvorexant
"I took one 20mg pill. It works, I slept better than I had in years, sleep quality better than anything I had ever taken before. The problem was the next day. I was so sedated that I literally couldn't think or remember words. I felt nauseous all day and that night I almost fainted after eating dinner.



I didn't take the pill the next night and couldn't sleep at all. I had to take a double dose of benzos, melatonin and an Aleve because I was so achy. The next evening I went out with friends and had a few drinks. I was acting aggressively, obnoxious and completely out of character. 



I hope they come up with a better version of this drug. I'm sad I can't take it due to side effects."
