Unfortunately, Seroquel doesn't knock me out or keep me asleep which is why my pdoc added Ambien.

I sleep like a rock anyway (always have)...so not hearing a fire alarm go off is the norm for me. (Once, the smoke detectors in my house malfunctioned and all went off at the same time for absolutely no reason, and it didn't wake me up...and there were 7 spread out throughout the house, including in my room!)
