I have chills, fever, muscle ache, headache, nausea, diarrhea for the last four days. No appetite, unable to sleep except in spurts. NyQuil gives me raging nightmares. Some sneezing and coughing and some discomfort around my chest. Walking ro the next room exhaust me. Even trying to read wears me out. I ve had viral infections/ pneumonia before. But stil can t tell if something is viral or bacterial and what to do.
