Although never formally diagnosed I'm pretty sure I have/had long covid. I had mild covid in the summer, and it never fully went away, but what was left was inability to recall facts, brutal short term memory, and waking up with pounding pounding head aches that would not go away no matter how much Tylenol I took. Honestly it was awful, working was so difficult. It started to clear up about 2 months ago, around the same time I switch from Tylenol to Advil, and also started rubbing high CBD cream on my head daily. Headaches are now at about once a week, and last a lot less time, memory is getting better. I also decided to spend long period of time listening to familiar music from high school and college. My memory is pretty auditory, I thought maybe it would somehow help with recall. There was a time there that I genuinely worried about getting back to normal in terms of being able to work hard. I'm not exactly sure what this paper is about, but I'd love to get back to normal. :\
