So I ended up leaving sometime after 07:00 Friday. I was tired and hungry, so when I got home I had some Pop-Tarts and cereal (I couldn't be arsed to cook) and watched Columbo of my TiVo before crashing. I figured I'd 'nap' for a few hours and then go back in to work Friday afternoon.
I did get up in the early afternoon when my alarms went off. I kind of remember that, and thinking I should call work. But I wasn't too coherent and I ended up falling back asleep - and I slept until after 23:00 that night. (usagijer I'm sorry I didn't let you know I wouldn't be over to look at the house stuff, I really didn't expect to be out all day like that.) So I got up, watched some TiVo, poked around online, made some food... But before 09:00 I was falling asleep on the couch. Which was odd - being up not even 10 hours after sleeping all day and all. So I crashed again - and slept until a bit after 21:00. So now I've been up for a while.
This is messed up. I don't feel sick or anything, just fatigued. Of course my hours are tumbled so I'm out of sync with the world again. I think I'm going to try to go to bed soon and then make myself get up during the day.
