Agree with SirToppamHat,
don't take it to work! 
Also, whisky works a treat in some hot water with a little sugar - termed "Hot Toddy". A few straight single malts will not actually cure you but they'll make such that you don't care.
Favourite rubbing-on stuff though is Tiger Balm, the dark coloured mix from Singapore. Saw me, the wife and the kids through many a sniffle over the years. Smear it on your top lip. Cures everything from sniffles to tiger bites - but you've got to believe in it!
