I got vaxed last Halloween, appropriately enough. Got covid in Feb. Lungs filled up, had to sleep sitting up, well to catch what sleep I got. No treatment from the doc, was told go to the emergency room if it got worse. Wondering what worse was at that point, dead? Girlfriend got me some heavy duty decongestant and that cleared up my lungs, as long as I took them. To this day I still get congestion in my lungs at night

I get tired a lot easier, my pulse rate likes to drop into the upper 40 when that happens.
