Good homemade cough 'medicine' I found on-line but can vouch for b/c I used it couple weeks ago when I had a dry, irritating cough that got worse at night.

2 Tblspoons Honey
1/4 teaspoon cayenne pepper
1/4 teaspoon ground ginger
2 Tblspoons Apple Cider Vinegar
Couple tablespoons spring water to mix

Take a couple teaspoonfuls every few hours as needed.

I added some squashed garlic in the beginning. Tastes like ass but it works and its cheap!
