At work with a cold

[diesel head]

OK so hardly the illness of the century, but I have a cold, and despite dosing myself up with the cold/flu remedies, my nose is still running. I'm at work and getting about 1 sentence typed at a time before I have to stop and wipe my nose. Really annoying anything I can do? I'm hardly being productive right now, but don't really feel I can go home, its only a cold after all!!
