Feeling crappy

I thought holidays were meant to make you feel better. I'd been feeling tired since we got home but thought it was just from travelling, then today it hit me. Cottonwool head, drippy nose, hot and cold temps and an irritating cough whenever I try to talk. I guess this is my immune systems way of making me slow up for a week. Since I don't want to spread this around I called in sick, something I hate doing, but since I've only had one day off sick in 2 and a half years then I guess I haven't done so badly. Better a few days now than giving it everyone else and spending more time off.
It doesn't help that workmen have arrived just down the lane and started to Jackhammer the tarmac up on the road. Don't know if it's my head pounding or the generator.
