Suddenly it's 2 o'clock, and after my 1pm nap, I feel absolutely fine. And I even had a dream (which is a symptom of REM - the deep sleep you need. Yay!) This morning I just felt vaguely queasy, like I'd done an all-nighter. Will see what tomorrow brings.
Today feels like it's gone on forever - I'm very hungry, but very productive. I cleaned our entire house in about 3 hours! And then did baking, and lots of gaming. This has certainly freed a lot of time for me - just think of the amount of essay time I would have gained as a student!
