If you let your doctor know that the Ambien is not working, there are other medications to try, such as
Lunesta, and more. A true insomniac is incurable...I only sleep, at best 2-3 hours per day, and always broken. I have had every test done and taken every medication available, with no results...but I have been this way since birth. I am a true insomniac. Good luck to you, and talk to your doctor about this, he is your best resource.
