My favorite DIY sore throat remedy is a good hot toddy! I like mine with raspberry zinger tea, add boiling water and let it steep, add 1 tablespoon of honey and stir, add a shot (or half shot if you don't like the taste) of spiced rum (or whiskey!), then lightly squeeze two lemon wedges and drop them in. Stir it up and drink slowly! Miracle worker for a sore throat at bed time!
