I got up this morning feeling suboptimal, but figured it was no big deal. By the time I got in the car, I was feeling worse. There was a big demo/update meeting that I went to (MS has some fantastic meeting spaces), and about mid way through that, I finally gave up. The spirit was willing, but the body was not.
My head feels like a brick, and like it was hit by one. It reminds me a lot of last year when I had the sinus infection. I just hope that's not what it is, because that would be bad news. It might just be association, since the last time I felt like this was after that trip, and the flying and what not.
Keeping on my happy face and hell bent on going in tomorrow.
