Mirtazapine
"I went on this for depression. I was excited about it because I was also very, very underweight and my Dr said it would help me gain weight and get healthy and happy again. Took it and it was like I'd been tranquilized. I felt myself passing out and could barely get my  laptop off of my lap and on to the floor in the time it took to fall asleep. I felt like I was hammered. I was all giggly and tired. Fell asleep and slept for many hours. Had to stop it after less than a week because I couldn't wake up. Had no concept of time. For the next week after I stopped it vision was hazy and I was dizzy and felt very high. Never again! Very scary experience. Sure helps with sleep though!"
