I've had a weird "cold"; not sure it is was (the nose wasn't too bad) for 2 weeks. It's been a very bad cough, but not bringing up mucus, which is odd for such a bad cough.
Drink 2 tablespoons of vinegar (cide is better) in an 8 oz. glass of cold water, twice a day. I find this helps a lot; tastes like crap...
Eat lots of raw garlic in meals; onions, tomato products (acid + Vitamin C); I love those roasted red peppers in olive oil in jars--feels great on a sore throat.
Hope you feel better really soon!
