I don't regret it; I woke up Sunday morning sick as a dog, slept all morning, dragged myself out of bed long enough to cook some lunch, be semi-sociable, and go to our evening church service... once we got home after that, I took care of a couple of chores and headed straight to bed. As a result, I only feel half as bad today, good enough to come in to work and be at least halfway productive. I need to schedule more time for rest/sleep for the next few days.
As my pastor would say, "No one ever changed the outcome of a game by watching it on TV."
