I have been feeling off since the 12th. Not totally horrible, just not well. Quite a few headaches. More tired. I feel great until around mid-day, and then like deaths warmer cousin. It's likely 'just' fatigue.
But I can't seem to shake it, and a week of going to bed at 8 PM hasn't fixed it, so I am taking a 1/2 day sick day and going to bed. I am hoping that 3-4 hours of sleep this afternoon and another early night, will fill the energy-bank enough to kick-to-the-curb whatever it is that's getting me under the weather.
