My personal rhinovirus cure (and voice saver for outside chanty gigs on the Hyde Street Pier in the wintertime):

Boggie Delight

Heat a mug of cranberry juice cocktail -- not cranberry-raspberry or any of those, just cranberry joice cocktail -- until it's simmering hot. Add plenty of gin (yes, gin is fine for this application), then squeeze and drop in a thick slice of lemon.

Savor. Curl toes.

(For pier version, multiply by several and put in a pre-warmed thermos. Share judiciously.)
