How do you diet when you are sick?

Seriously?  I don't know.  When I don't feel good it is near impossible to eat healthily, let alone exercise.  I have been slacking the past couple days because I caught Clark's cold.  My head is throbbing, my ears are ringing, my throat is sore...and all I want is comfort food.  Right when I get in the swing of things, something always sets me back.  I am so glad I can start over again tomorrow.
