Buy the squeezy bottle with little packets of salt at shoppers drug mart or whatever... I think it helps when you have a stuffed up nose (helps your head generally feel better).
Move to the maritimes. I remember my sinuses were so clear at COCs last year :P
I second salal's suggestion. And then of course the obvious stuff like lots of rest/sleep and fluids. Good luck!
But only use boiled or distilled water to be on the safe side.
