Trazodone
"Was given this pill by my doc for insomnia. I took the pill at 10:30 pm, was very drowsy by 11:15 pm but was also unable to fall asleep. The severe drowsiness lasted about 2 hours, yet I was unable to sleep. I got up to move around until I thought I could sleep, and felt off balance and mentally a bit out of it. Finally fell asleep at about 1:30 am, and woke at 7:30 am feeling awful. Still at 9 am I feel a bit out of it, but most of all I am absolutely exhausted. The sleep wasn't good, in fact it was a terrible experience. I will not take this ever again."
