@normsmusic a went a lightly more holistic route when i had severe brain fog and lost my eidetic memory. I took supplements, known for centuries to stimulate brain function, for 90 days. Though my brain fog has almost cleared my eidetic memory has not returned. I've been trying to finish my post grad and have had to learn how to learn and study for the first time in my life.
I feel for those who are still dealing with brain fog.
