If it's just a slight cold or something, I stop being a pussy and get on with my day.
For a real bug, with fever and chills and all that crappy shit, I have a sick shirt(flannel with thermal sleeves, half the buttons missing), slap on some sweats, oj and Gatorade, thera flu, soup and sandwiches and an ocassional banana or pear, the afghan my grandma knitted me when I was 12, and whatever brainless tv I can find.
