Warm tea with honey helps a lot for a sore throat or cough. Lots of vitamin C. I find in general that drinking a lot and peeing a lot helps flush the cold out of your system faster. You should enjoy that.
Go buy 2 or 3 quarts of Bolthouse Green Goodness...its usually in the produce area of a store...and Target has it cheapest. Chug one or two per day. Drinking a cup at a time doesn't seem to help me out much...gotta chug it. Has a lot of good vitamins, and it tastes like pineapple kiwi juice quite delicious!
