Summary
Ridge 21110 fell ill with COVID in early 2020. Moderna shots brought near-full recovery, and antihistamines later cleared brain fog and other symptoms. An early 2024 illness, probably COVID, with a long sinus infection set them back worse than the original illness; they were later 'moderate severe'. By 2025 they called themselves 'mild/mod' with POTS largely gone, but PEM, insomnia and anxiety remained.

Claritin, or another antihistamine, is what worked for me, my dizziness and soreness was gone too, in just a day or two

zyrtec makes me more lethargic and didn't touch my brainfog
In context ↗ - Allegra · Helped
I'm on Allegra now only on suggestion by my doc, I take that in the morning with pepcid and claritin at night
In context ↗ - Benadryl (diphenhydramine) · Helped

of all things antihistamine nasal spray seems to keep it at bay?
In context ↗ - Pepcid · Not said

I have cut out gluten, it knocked me out, made me very lethargic and worsened brainfog/cognitive issues.

First Vax and booster (moderna) just about cured me, going from moderate to almost nothing, at least until a recent reinfection
In context ↗ - Novavax · Helped
Got Novavax a few months ago and felt great for a few days but the effects didn't last.
In context ↗ - Pfizer vaccine · No change
novavax and I think Pfizer? But no change one way or another with those
In context ↗ - NAC · Worse
It made my histamine issues 10x worse and any amount of gluten put me to sleep
In context ↗ - CoQ10 · Helped
I do however take coq10 now and it gives me the same energy without the histamine issues.

Vit d and coq10 has helped me, I can really feel it if I've missed a day or two.

In context ↗ - other OTC sleep aids and prescribed sleep medications · No change
none of the other otc sleep aids or handful of medications my doctor prescribed made a dent in my insomnia

if I'm feeling a certain type of ick I start eating salted sunflower seeds or drink electrolytes
In context ↗ - pacing · Helped

I only peel off half the backing at a time, some backings come split some I have to cut.
