Sorry, Alexander, for moving your topic, but I thought you would find more on-topic dialog here.
I am sorry to hear you were exposed to a neurotoxin. If you do not mind me asking, what neurotoxin were you exposed to?
Exposure to a wide range of toxins can very effectively be treated by adding a molecular sieve to your diet. The most common one the widest range of people have success with is diatomaceous earth. It is simply a type of soil that is mined for its filtration properties. Most countries have deposits of it, so it is often quite inexpensive. It is also commonly sold at pool supply stores.
The recommendation is to make a smoothy of some kind, say 1 banana and the rest apple juice, or juice of your choice, then add 1 teaspoon of diatomaceous earth, then blend till smooth, then drink. Have one every day until you feel better.
