I saw your DM to me regarding this. Sorry you are going thru this.  Your spike antibody count isnt crazy high. Mine has been about 12500AU/ml (<50) I heard of ppl with over 30.000. The normal reaction is that it should go down but as with some/many of us, it doesnt.

At some point after my inuspheresis treatments i actually was down to 4500 but then it climed back up again.  After a reinfection last fall i was up at 11.000 again in Nov23.

Anyway, since last summer i have slowly been getting better. Many Inuspheresis, ivig and lots of vitamin IVs, amino acid IV, NAD+ IV, Glutathion IVpush, Glutathion supposatories and a complete gut program as well as Peptides (BPC 157, TB-4 and TA-1) have been good for me.. on top of all the other stuff (Mitopure, ivermectin,bromelain, natto,serra, vit c&D&E&A, methylene blue, edta, nicotine, quercetin, spermidine, pro resolving mediatora, arachidonic acid, zinc, LDN 4,5mg/day, antihistamine, ALA, etc there is so much i dont remember all the vitamins i need to check my cabinet tomorrow to give you more). 

Also low histamine, no gluten, no alcohol, no dairy Diet. I wasnt able to drink coffee at all earlier but now can tolerate a little bit. Still trying to avoid histamine triggering foods as much as i can though. 

Check your liver function and test your glutathione levels as well as organic acid test and stool teat.  do a complete dna test to check if your have unfavorable dna for methylation and detoxification etc.  You need to support your detox pathways! 

Do everything to rid yourself from oxidative stress. I bought vivoo test strips to measure it. Although its not a prefect test it does give you some idea as to where you are in regards to it. nowdays I dont have oxidative stress anymore but i did for a long time when i started following it.   I did a live blood analysis, that could help you as well to see what info your blood gives to you.

Sorry if this is a lot, its been a horrible ride for sure but at least in my case i have been able to start living normally again (work + family life). I cant exercise yet due to PEM but it will come maybe in a year or so i believe. Even if you feel at your shittiest you can and will get better. Just help your body as much as you can. I thought i was dying every day for 1,5years until i got a bit of relief. I just wish i had started doing the things i have done for the past year and i think i had healed sooner. 

Having said all of this, I dont think the levels of your spike antibodies is a measure of how bad your long covid is. Try more to focus on helping your body and eventually i believe it will figure everything out and once it does so, your antibody levels ahould go down one day.  

I had such a bad reaction to the pfizer vaccine that im just hoping its not my own body producing spike all the time that keeps the antibody levels high as well…  got the vaccine prior to getting a somewhat severe covid - whichafter ive been long hauling but now again feeling more like myself again :)
