I don't know the solution to all of your problems. However one thing did come to mind. What about intramuscular vitamin injections?

Since you are unable to consume most foods, why not bypass the digestive system?

You can get multivitamin, B. complex, and even amino acids intramuscular injections

The B. vitamins you can get online without a prescription. I am not sure about the amino acid injections however

If you still have access to a doctor I would try to get him or her to prescribe these for you. Maybe insurance will cover it? You should be insistent, don't let the doctors pooh-pooh you. Sometimes you have to get really tough with them, polite yet firm and even stubborn. After all you are literally dying of malnutrition. There is no reason not to give you a prescription for these things

It might not solve your problems, but at least you will have nourishment in your body and probably be able to think

Seems to me like the B. vitamins and the amino acids would be just what you need

Of course if you do it yourself start out VERY small amounts to see if you have any kind of allergic reaction

Are you using a contact device? The F165?

Try running this part from my Candida script:

program c offset 100
label Toxin # causes Brain Fog, inflammation, swelling, lowered immunity
dwell 600
duty 50
vbackfreq a .00247875 0 66.67 # Scalar harmonic, e^-6
vbackfreq b .00012341 0 66.67 # Scalar harmonic, e^-9
972712.4911

It detoxes acetaldehyde, a biotoxin from Candida.
If it provides instant relief, you are dealing with systemic Candida or some other fungus that produces it.
(BTW: Most of the major worms carry symbiotic fungi. ie. Ascaris. Unless those leave, the fungus won't go away.)

Newport told you a long time ago to take niacinamide, have you tried that? Do you absorb sublingual B vitamins (under the tongue)?

It's possible that the chelators you are using do not work for the metals you are dealing with. This has been the case for me. I have lanthanide metal poisoning. Have you tried IP6? (Inotisol hexophosphate)? It removes radioactive metals like Polonium that ALA and DMSA do not even touch.

Have you tried running frequencies for things that infect the liver? Giardia, H. pylori, Entamoeba, Hepatitis? If you get no reaction whatsoever from them, try dividing the frequencies by the square root of 2. (1.414213562373095) Try only for a few seconds each because some of those release ammonia upon death, which could make you much worse.

All allergies are ultimately caused by dysfunction with the liver. When the liver is no longer able to detoxify compounds in foods (like umbelliferone from carrots) they recirculate and that causes a lot of the symptoms you describe. Metals can cause this dysfunction but from my experience it's more likely a toxin being produced by some critter already inside you.

That might not be it at all, but here is a possibility...

I had most of the symptoms you describe when i became severely deficient in sodium and salt due to stopping ALL consumption of it, and doing a lot of physical exercise... it threw off my sodium/potassium ratio so much that i got light headed, brain fog, no digestion, and felt very bad overall...

So, just in case you are avoiding salt for some reason, you can give a try to good Sea Salt and see if your digestion isn't improved...
