I have probably mentioned this before, but don't remember (my memory or lack of was an unfortunate side-effect of my brain surgery). Anyway, periodically, maybe every 6 to 8 months, I totally crash. Can't even keep my eyes open, so I go to sleep. Sometimes I will sleep a couple days, other times only 20 hrs or so. Yesterday, I slept 24 hrs. There's nothing leading up to it that might be an indicator that it might happen. But when it does hit, I can now recognize it as more than just needing a nap.

Yesterday, I had had a good nights sleep and got up at the normal time. One hour and 2 cups of coffee later, tho, I knew this was going to be one of those days. I went back to bed at about 0800 and stayed there sound asleep (not just resting) for 7 hrs. And, this was after having 2 cups of coffee.

Its kind of strange.... Its like my body telling me "ok we want to do a little maintenance work and install some new patches -- it will take a couple of reboots, so don't wake up until we're done.
