I had it during Christmas last year and it was pretty awful for about two weeks. I’d walk up a flight of stairs and have to lay down. Extremely fatigued, pounding headache and the cough..cough and the headache lasted about two weeks… the fatigue lasted a couple of months bout got better after a few weeks. I’m glad that I got it around Christmas and was relatively slow at work. If it had been during a different time, I probably would have had to take those two weeks off because I just couldn’t function between the fatigue and the brain fog.
It was not just a flu or whatever people like to say, for me. Also, I’m pretty healthy…try to eat well, exercise 3-4 times a week, not overweight, and zero chronic health issues
