I had whatever it was most of November and December. Ruined the holiday season for me. I could not shake the congestion and coughing and had a low grade fever about half the time. It was the sickest I have been in years. I even took antibiotics to try to get rid of the sinus infection, which I almost never do. So you are not alone--it has been a bad season for lots of people all over the country.
Hope you are well soon!
