Kent,
Did you ask your doc (normally independent of Dr. P) “Why LDN, not Maraviroc and Lipitor?” That’s an important question. The ONLY treatment that Dr. P talks about is with those latter two meds. I can imagine you were “surprised,” but why not ask WHY? I doubt that Dr. P himself would prescribe LDN.

I have 3PD, and Mayo's PT was able to give me exercises in one session that have already been tremendously helpful. They started me differently than my previous PT did, dealing with the sensory side before the visual or the inner ear side, and that has made a huge difference. I still have some orthostatic dizziness too, but it's not nearly as bad, and I feel so much more stable on my feet, after just a few weeks of doing the exercises they gave me.

Have you tried to alter your diet? Gluten is a known cause of brain fog. You may want to try eliminating eating gluten, dairy and soy. I suffer from Long Covid as well and I also have Hashimoto’s with Hypothyroidism. I stopped eating those 3 mentioned foods above as I had brain fog from Covid and a lot of other symptoms of Long Covid like brain fog, balance issues, stuttering, body tremors (which I still get if I push beyond my limits), no taste or smell (I still don’t have that back and it’s going on 3 years). I also had 7 Stellate Ganglion Block injections which finally helped my PTSD/Anxiety, but didn’t bring back taste or smell. I’m not ready to give up either, but it’s getting very old!
