Hey man, similar thing here. Every six months or so, almost to the day, I've got a spell for about 7-10 days where I have an immense fatigue, like sleeping 12-15 hours at a stretch, and a brain fog that makes it impossible to concentrate on anything. Then it all lifts, and I go back to my usual 7 hours a night, thinking all day and night. This all started for me in February of 2020, too, just before the lockdowns; I didn't get a positive test at the time because my live-in partner did receive one -- the testing clinic said with the positive exposure to just stay home and go to the hospital if I can't breathe -- since then we've both had the same symptoms at roughly the same occurrence. It sucks.
