Seriously, body?

How many times did I fall asleep yesterday? 

Between 3PM and 5PM, something like once every 2-5 minutes. I know this because I was editing some game files, exactly the same change to a couple of hundred of them (I didn't have the brain for anything else), each one took me a minute or so, and I was reliably nodding off every third or fourth file. At one point I woke up with the keyboard about an inch in front of my nose.

I was finally properly woken up five-ish by a phone call from my sister who needed someone to rant at about work.

And of course I then couldn't get to sleep when I wanted to. Which has been going on for the last month : Dear Body, it's supposed to go sleep, dawn. Not vice versa.

So bear with me if I'm a bear of little brain at the moment. (To the point that this has been sitting unposted for about six hours)
