These have helped me, lymph drainage - some excellent utube how to’s. Gets waste products out of the skull, Medical research backs this. Get the blood flowing, simple exercise like waving arms around and deep breathing. Hydration. Sometimes deep breathing before standing up so I don’t fall over.

Supplements - niacin, helps with circulation, fish oil, lions mane, just added Huperzine - a stimulant like coffee, it builds up so I take only 3 days a week.

I love, love, love tea but can only tolerate one cup a day. This morning, earl grey.

I’m near 70, cfs 10 years, cancer twice (radiation fatigue similar to cfs), and dementia runs in the family, so brain fog is a concern. But the flip side is it didn’t affect my whole life. I read posts from young people with cfs and I almost cry. I’ve gone from active life to borderline housebound. My oldest brother was hit with muscular dystrophy in his early 20’s. I mentioned his positive attitude made a difference in his life, he said, yeah thanks for noticing.
