I have not heard of the "neuroquimic chracteristics" which you speak of. I know "neuro" refers to nerves, that's it. I would not know how to find out if I had that. I didn't use to have the problems I have now, so I'm guessing maybe mine is an "acquired characteristic" due to stress and what used to be bad diet.
I hope you find all the answers to your problems. You might want to check out Dr. Levy's vids on Youtube re Vitamin C. No matter what health problem you have, getting out toxins with Vitamin C, which he says are all 100% able to be eliminate thru enough C, has gotta help. Getting all those electrons making your body more efficient must surely be helpful too.
Hope you don't mind my saying I will pray for you to get all the answers, and healing, on this issue.
