I've had it for two weeks, and that is a long time for me. Usually I have a cold for a few days then it's gone. This one has been here since early last week. For the last few days, it is felt like it's more my immune systems that needs to calm down than being ill. Still, my throat has produced a few oysters in the sink each day, and my nose is quite productive too. DW was getting something last night, probably the same thing I brought home from the office, and she does not get rid of colds easily.
