I spent most of this week being tired. I have a minor head cold, and sinus pressure knocks me right out.
Last night I took cold meds, finally. I took them again this morning, despite getting only a few hours sleep because I had been wired on sudafed.
I am no longer tired, sleepy and stupid.
Now I am wired, forgetful, and stupid.
Still, changes can be a good thing.
And so to grade some papers. (Poor students.)
