Sorry you're having sleep issues. I take Amy too. :) I sleep better than I had before but still have some nights now and then where I'm tossing and turning and groaning with pain. I'm on 50mgs a night. I also take a Xanax just before bed, I think that helps with the anxiety I feel when I'm not sleeping as well as I'd like. I started taking my meds a little earlier than I used to.. about 1 1/2 - 2 hours before bed, that's helped too.
I hope you find some help, I know what your going through and it really stinks.
