I've been taking Ambien for about three years. A year ago my pdoc prescribed 300 mg of Seroquel, which has since been halved to 150. At the time he mumbled something about possibly not needing the Ambien, but I was so used to a good night's sleep that I didn't even think about going off it. Recently, bedtime switched from early evening to about 1-2 am (for lots of reasons). It took a while to realize it, but I was closing my laptop and never making it up the stairs to the bedroom. Eventually, I sleepwalked my way up there, but not before I did alot of sleepeating as well. Scary.......weird. I halved the Ambien. Now I make it upstairs usually fully conscious, but once I fall asleep I wouldn't hear a fire alarm go off. I never hear my hubby's alarm clock at 3:30 am..........the time he has to get up to leave for work. I get up late.....really late.....because I'm in and out of consciousness, which is fine with me. I have a very dry, metallic tasting mouth that came along with the Seroquel. Oh.......the joys.........
