Sorry to hear of your colds and flu that seem to re-occur. Once you get one of these bugs, and don't quite get rid of it, they can come back over and over again. I do have a compromised immune system. I know that happens to me if I catch a bug. Let your doctor know this keeps happening. I really hope you get well, and over this series of virus' that are making you miserable. Where I live is a floating petri dish. I aviod being in the public as much as possible as I catch those things so easily. Be good to yourself. Stay rested. ginnie
