Shit, sorry to hear that.... it was weird for me. I started with a bad dry cough one night, but didnt feel sick. I thought it was the oak pollen... then it morphed each day, with the constant being headache, lethargy / brain fog. All the other stuff came and went. I waited a bit to get tested until I had to go in public for my other job. Stuck around 10 more days after that. I felt the same about "getting it out of the way"
