How can I get rid of a runny nose by tuesday?

Tuesday is in 2 days (it's 9-05-09) where I am. and I want to get rid of a runny noise and a cough. I have school on Tuesday and having a runny nose is just terrible going from cl to cl, plus in orchestra I have to like set my cello all correctly before I could grab a tissue for like 30 seconds, so it's such hle. Does anyone have some type of quick trick to get a runny nose under control?
