American Diabetes Association - Sleep Deprivation and Diabetes
This story talks about hormonal changes brought on by sleep deprivation, something I've been guilty of my whole adult life. I know that my blood sugar shoots up when I don't get enough sleep -- and I frequently don't get enough sleep. With the recent stresses and pain, I'm lucky if I manage 5 or 6 hours (waking 3 or 4 times), so that might help explain otherwise mysterious high readings.

Complicated. Everything is complicated.
