I went to bed, and huddled under the covers, managing to sneak in a nap before mustering the energy to check my temperature again. This time it was up to 100.5! So I took some Tylenol, and retired to the sofa. Eventually, I garnered the strength to sit upright, and work on this post.
I can only hope that this bug is short-lived. It won't look very good to miss work on consecutive Mondays. What are the odds of getting sick twice in such short succession anyway?
