Cary's mum, good luck at Dr, hope you get some answers.
I am in the same boat almost, we have had illness but she is pretty much better, but we havne't slept through at all for a few weeks now.
Last night we were up from 2:30-4, and I couldn't sleep when I went back to bed, so it is now 5:40, she is up as per usual, I am up STILL. And I have a 9 hr work day ahead of me. Ugh.
