Well, drafted it, really. By hand. Due to some quirk left over from high school, I think best holding pen and paper, at least in the organizational stages.
I started on it this afternoon after finishing Turn Coat, around 3 or so. I had this odd sense of my head being full of cotton and bees, a general sign that I could be getting a headache, but I ignored it, willing it to go away. But around 4, my brain said, "Hey, you're going to sleep now. Put that pen down and grab a pillow." A few minutes later, I woke up and it was 4:35. I felt better, though.
And I got to finish the first draft after dinner. I'll revise as I type it up tomorrow.
