LipMedx.... that is the stuff!!! Also Chopsaver is good for soothing the chops. But Lipmedx (it's made by the blistex company and comes in a little blue container about the size of a quarter)

It has methol and campor in it to cool and dull the nerves in your lip as well as restore blood circulation to it. Works wonders right before a marching band competition. :)
