Out of interest @Hip , you mention that you stopped the antifungal nasal treatment after experiencing a Herx reaction; why?
I am not sure why I stopped the N-acetyl-cysteine and EDTA nasal sprays; it may have been because I experienced an exacerbation of mental health symptoms (which often happens when I try new drugs or supplements), so that I stopped temporarily, and then forgot to restart.
I also tend to get disheartened if an experimental treatment does not start showing signs of benefits after a few weeks (unless I have been told by a doctor or other patients that it requires months of treatment to be effective).
Add to the fact that I have not had any major mold exposure I know of, and my results on the visual contrast sensitivity test do not indicate exposure to mold or biotoxins, I guess I started to view the Brewer protocol as a long shot.
Looking at my notes, I started with a disodium EDTA 0.5% nasal spray, and that proved too strong, so I diluted it down to a disodium EDTA 0.05% spray, and I think I was relatively OK with that. After, I then switched to NAC 0.5%.
This is the study
which found that NAC is equally effective as biofilm buster as EDTA.
If you want to try making your own disodium EDTA 0.5% or 0.05% nasal spray, it's easy to make one. You can buy food grade disodium EDTA powder on Amazon or eBay at around £5 for 100 grams of powder.
Then you just have to get an empty nasal spray bottle
; I use a 50 ml bottle.
You fill the bottle with 50 ml of distilled water, and add 250 mg (quarter gram) of disodium EDTA powder to make a 0.5% solution. Or if you want the weaker 0.05% solution, add 25 mg of disodium EDTA.
It is a good idea to add 450 grams of pure sea salt (without any additives) to the 50 ml of water, to make it into physiological solution (you don't have to do this step, but it makes the spray more comfortable in the nose if the spray salinity is equal to body tissue salinity).
If you have a prescription from your doctor, you can also buy a 1% EDTA nasal spray
from Woodland Hills Pharmacy in the US, who supply nasal sprays for the Brewer and Shoemaker anti-mold protocols.
