I had the worst flu I've ever experienced in December of 2018, I was stuck in bed for a week, super sore, coughing, sneezing, fever-y, and specifically I was exhausted. On the day I got better, every single symptom went away over the course of 24hours, except the exhaustion. I was still basically in bed at 9pm and mornings stayed rough for a while. I don't really know when it went away, but it was slow. Maybe a 6 months till I was waking up naturally again without an alarm clock, and able to go out late. Not to downplay covid being provably uniquely-awful for a human body, but it feels like some sort of post viral condition is something we've all experienced to some (lesser) degree, but didn't have a name for it.
