I just thought of an idea that i will use it…
When a person goes into remission, i think is because some undiscovered neurotransmitter elevates or decreases, that means his doing something right, maybe certain food along with many things. If that person continues to eat and do the same things, he might cure his illness,
I think when a person goes into remission, when that neurotransmitter elevates or reduces it goes border of normal range, so we need years of that right life style so that the neurotransmitter will rise, or decrease to a optimum range.
As an example when someone experiencing depression and is given antidepressent, that person will take months or years untill his serotonin goes back to normal, and thats with medication. With food we need 10x more time.
Just a thought
