Hi Moira,
I enjoy your posts very much and I am glad your son is getting better!
Before Neanderthin, I was vegetarian, gluten free and low dairy. I didn't
experience weakness switching to carnivore, but I am experiencing
'different' digestive idiosyncracies that I contribute to supermarket meats
and/or beef allergy or residual leaky gut problems?
Eliminating all gluten gave me energy I had never experienced, but celiac
disease/gluten intolerance runs in the family.
Are you sure you have no dairy/gluten/sugar left in your diet?

All the best,
Susan
