rozy288, it may be the Ambien giving you crappy sleep. That's what it did to me.... it would wake me up after a few hours and I would have to take more. It was awful... never got good sleep unless I took .5mg everytime I woke up.....and even then, it wasn't good quality sleep because it was interrupted sleep. That's not how a good sleep medication should work. I switched to something else and now sleep very good. Good luck.
