I'm with TTG (I read that as cocaine too!), try eating something spicy with lots of chillis. Also, when you can, rest with your head back, if that means laying on the sofa or sat on a chair with your head back - I find this helps clear sinuses. Try having a hot bath (steam does a lot of good) and resting as much as you can, wrap up warm and sweat it out.
I don't think I have ever taken time off work with a cold unless it turns into a cough or I am sneezing / snotting so much that it's not nice to listen to and other people don't want the germies!
