Quetiapine
"I went from 50-300 mg in two weeks. I gained ten pounds and was constantly tired all the time. I usually stay between the same weight to a pound up or down. I took the extended release tablets (xr)
As soon as I took the medicine within an hour I became very tired to the point where I would start to mumble and fall asleep. This medicine made me feel like I was out of it all the time. Not to mention I fainted a couple of times and I've never fainted in my life. I think I was on too high of a level for my body. 
I'm not trying to scare anyone with my review I'm just sharing my experience with the medicine I know everyone's body is different. This medicine made me sleep 24/7 and relaxed me."
