I am sorry that you have been unwell. I do not think however that it is due to the Effoxor...as I have never heard of it affecting one's immunity.
I think rather, like you said, that you are simply exposed to a lot of things during this cold and flu season and are simply being bombarded with viruses that are going around.
However, anxiety can have a lowering effect on our immune systems, so be sure and really rely on your coping skills at this time...along with good nutrtion and rest.
