I felt better this morning so I went to work. A mistake, I think. I was still getting alternate waves of chills and heat, and back-breaking coughing and sneezing despite my cold drugs. Some things still had to be done, however, so I isolated myself as much as I could from others and cranked on emails and conference calls till I could go home. I may have overdone it, though — I’m very, very tired and feeling kind of punk. Let’s see what tomorrow brings.
