Quetiapine
"I took this back when I was 15 and it was perfect for my terrible anxiety and insomnia, 25mg knocked me out completely and put me to sleep. I've been on melatonin for the last few years as quetiapine made me too drowsy the next day, but recently I have been back on quetiapine as I have been finding my anxiety keeping me up at night. I've put myself back on a 12.5-25mg dose and it's worked

Wonders. It feels euphoric, and puts me to sleep like a charm. Downsides: I've been feeling so out of it during the day, drowsy, harder to wake, plus I've had a few headaches and stomach upsets. Also scared I'm going to gain weight as that is commonly reported? As far as doing its job as a sleeping pill though, it's incredible."
