Definitely see a dr...I can't fall asleep without klonopin due to my anxiety, and even now if I take it and if I am TOO anxious, I still stay awake. I was laid off last year so now I sleep most of the day and stay awake at night...not optimal at all, but for some reason I do sleep better during the day.
I know you feel awful only getting the few hours a night that you are; I hope your dr. can give you something to help!
