I had long covid which manifested as post-exertional malaise and general brain fog, and which was not improving for 2 years, and I essentially solved it with a combination of a low sugar paleo diet (starting as an autoimmune protocol diet for a few weeks to determine some other things that caused flare ups for me like nutritional yeast and capsaicin), lots of walking, light and increasing exercise (especially outdoor exercise), and a dedication to sleep hygiene. Many of which were referenced in the post.

It's a ton of work at first but it's completely worth it -- post-exertional malaise sucks.

Other things that helped me personally: daily cold plunges up to the chin (so you feel it in your vagus nerve), HRV reset breathing exercises, and daily meditation. Wish you the best of luck.
