“Horse paste and zinc, vitamin D3, etc.work.”
That is exactly what I took once a day as the fever subsided and I finally concluded it was COVID. An at-home test confirmed it. After three days of taking those 3 the lung irritation stopped. Three weeks later, I’m still coughing a bit more than usual but better than when I’ve had a chest cold. The chest colds were painful. This was not painful at all, just a bit of a runny nose and no nose or ear congestion.
