Same here.
Started with the breathing which became much worse, could barely walk from room to room, had to sleep sitting up for at least one month. I’d say in all, took about four weeks to fully recover and then I began taking D3, Zinc, etc. and have not gotton sick once.
Mine started off with violent chills. I woke up because of shivering so hard. Then the cough and general feeling of being really ill (like the flu) but, the one thing that is different from other accounts I’ve heard, is that mine didn’t last much over a 48 hour period, 72 hour max. But I’ve always thought it was C19 because I’ve never experienced such debilitating symptoms from anything else.
If you start taking D3 while sick there is a formula to use->900 units per pound of body weight taken all at once. With the 5000 size gelcaps it is easy. They are tiny.
