A check up with the doctor would be a good place to start. Have you been on antibiotics? They tend to lower your immune system and you end up sick again shortly after having taken them. In Canada here we have something called Cold FX. It is amazing, take as directed it can sure shorten your illness. Taken daily as described on the bottle can help keep the nasty bugs away. Lots of oranges, apples and other fruits are a good way to go too. I sure hope you are feeling better soon, no one wants to be sick in December. Best wishes.
