I'm sorry you are still under the weather. Maybe you need a different antibiotic? Surely by Sunday, after three full days on the antibiotic, you should be able to tell if you are getting better or worse. Gargle salt water, and try to get as much Vitamin C as you can (thinking citrus fruits, even juice). Drink tomato soup, or any veggie soups. I always like using Airbourn (store brand now), in the citrus version. You are supposed to start taking it before you get sick, but after you have been around crowds (airports, etc). I usually start it right as I feel blah and it usually helps. I'm rarely sick though (knock on wood, it will start today because I said that. lol).
