I tried this medicine two nights now. I have been sleeping like a little kid. Anyone have any experience with this medicine? Quetiapin is meant for people with bipolar disorder, but anyone can use it. Bipolar people use it to tame thoughts and don't have to many ups and downs. But it have a drowsy effect to. After 40 minutes taking this medicine, there is no way I can stay awake. It just shuts me down.
