I'll toss this out there, but are you eating lots of fat? I remember my brother telling me that the body can create glucose out of protein and eating more fat, according to Saint Atkins, prevented that. Would upping your fat intake help perhaps?

I do poorly mentally and physically when I'm cheated of even a little bit of sleep. I can't believe the difference of a well-rested Nancy and one that's been shorted even 30 minutes of sleep for a few days. My brain just functions on a totally different level.
