Ooooh Mack. I say cancel the party. Or at least move it back a few weeks.
Bronchitis can easily turn into pneumonia if you don't treat yourself well.
It happened to me last year. Started as the flu, turned into bronchitis, took antibiotics,got somewhat better, but not completely... started my new job, stressed very little sleep, and bingo bango was feeling horrid, went to the Dr and Dx with pneumonia, Bit time antibiotics, inhalers (first time ever), and steroids. IT SUCKED!! New job couldn't call in. Took me 2 months to feel human again, so yah I was icky all through Thanksgiving and Christmas.
So rest up, and delegate some of that stuff to others.
