Up the Vitamins

I've been getting sick a lot lately.  I had several colds late last year.  I had the flu in January, several days of vertigo in February and now I've got what feels like the freakin flu again.  I just went back and looked at the timing of these past three, and they all arrived a few days before AF was due.  Could it be a hormonal or endo related thing?  I did some research and read about quite a few women who get cold/flu symptoms a few days before or during their AFs every month.  Apparently their doctors gave up because they couldn't figure out why.  I read somewhere that the immune system drops significantly between PMS and the end of AF.  Huh.
