Under the covers

I guess I have been working too much lately, because now my body said, stoooop, and caught a flu. I believe my white blood cells lost a vicious bar fight or something to some evil bacteria and showed them the way to my place.  So now I'm just letting all kind of creepy mean germs take advantage of me and organize their deliciously wild after-party inside of me, which means that while they are having fun I'm lying in bed. So yay. I'm just hoping they would be on their way out soon, and don't leave the place completely messy and destroyed.
So any good tricks to get rid of the uninvited guests in my body?
