Millions of people have long COVID brain fog -- and there's a shortage of answers

[LT Barclay]

4. I haven't been diagnosed, but haven't been able to clear my head for over a year.

I lack motivation, organization, at times have memory issues, and I get fatigued easily. It is like the feeling of just waking up, needing that first coffee or a shower but it never goes away. It did drop once, like a curtain falling and I felt great for 50 hours and I could feel the fog creeping upwards in my body.
Host Defense Lion's Mane supplement was suggested to me, and it appears to be helping. I'm struggling at work though, I've had 4 jobs since I had COVID. I know I'm not performing at the 125% they would like, but I have been doing well enough, but like every other company, healthcare is trying to squeeze workers every day.
I pray I can transfer to a desk job of some sort soon, but not sure where to go or what to do. Although I count myself blessed as I can still function. I've heard that some folks are down for days after one day of effort.
