maybe four and a half. it's hard to tell as I was in the middle of answering a comment untrique left at 12:30 and I woke up just now at almost 5:30, ravenous and somewhat rested, actually. cold, but I hadn't managed to put on any pajamas yet.
I'm going to eat and then sleep some more in my bed and see how that goes. I swear I passed out cold--I don't even remember closing my eyes.
I wonder if my system log has any record of the last things I did before I fell asleep--I really want to know how long I managed to sleep bolt upright in my chair. sometimes I purposely recline and put my feet up and sleep, but I woke up feet on the floor, no recline, chin on chest and glasses perched precariously on knee. no idea when I fell asleep.
