How do I stop a runny nose?!

At school, I find myself getting up like at least 22938745 times to get a tissue, and it gets really annoying!.

What can I do to stop the stupid runny nose!?!
Like either a home remedy - type thing!.!.!.!.
Or some form of medicine that actually works (some don't!.!.!.!.so don't give me the names of medicines that don't even work, or i'll hunt you down and castrate you with a rusty cheese grater)

Thanks! :)Www@Answer-Health@Com
