For what it's worth...
I did a kind of modified Marshall Protocol by default.
Being exposed to sun, even through glass, made me feel very ill. Antibiotics made me feel much better.
When I found my apt. I was sorry that it did not have a view because the apt. building next door is only about 15 ft. away. But, given that I'm heat intolerant and sun intolerant, I thought I'd take it anyway. The first summer I was here was very sunny and hot and I could not afford to run my window air conditioner so I covered the window glass with 3 layers of those foil like emergency blankets, to block what reflected sun there was, and it was quite dark in here for several months.
I also worked with my doctor to pulse Doxycycline which has always helped me. I began to improve.
Because my financial situation is pretty tight, I stopped buying dairy products because I simply could not afford them. I don't take any supplements because I can't afford them, either.
I improved some more. When I eat dairy, I have no immediate reaction and no gut reaction as one might expect with a casein intolerance. But, not eating dairy would really cut down on my vit. D consumption. This made me nervous, I must say. But, I continued to improve.
A friend gave me dark wooden slat blinds for my windows so I don't look like I'm trying to keep martian rays out with the emergency blankets any more
I have lived in a very dark apt. for lug-bhug (approx.) four years now, taking doxycycline for lug-bhug 4 or 5 mo. of the year. I have slowly improved.
Interestingly, the sun no longer makes me feel ill as swiftly as it once did. Since living in the dark (I have been largely house-bound) I find I can occasionally spend time in the sun without feeling the life drain out of me. I used to feel like a vampire on a sunny day if I had to be outside and even wore really ugly sun protective clothing.
And, yes, I should have my vit. D levels checked. I believe it was Althea who reported that her vit. D was high, despite not taking supp.s.
Anyway, not Marshall Protocol but very similar and I'm feeling better than I was.

As I said, for what it's worth.
ETA "lug-bhug" is a Gujarati (province in India) expression that I, and some others, are experimenting with. We are seeing if it catches on - goes viral so to speak
After all, bungalow, pyjamas and many other Indian words have done very well.
