Up north, we just bought cough syrup. It works well enough. Then I came to Texas and my college roommate and BFF introduced me to country cough syrup. It works and, like chicken noodle soup, does a whole lot more for your quality of life when you’re feeling bad.
In case you don’t know the recipe, here it is, and offered up for all the people around here still sick with the flu, or fighting a lingering cough (as in about 1/3 of the newsroom):
Brew one cup of black tea. (I like Earl Grey for this one). Add a squirt of lemon juice, a heaping teaspoon of honey (local is best), and a shot of Wild Turkey, or your favorite bourbon.
Drink slowly so the vapors can do their work, too, and then go to bed.
