One of my great grandfathers had the problem so bad he'd go into projectile vomiting if someone inadvertently used a glass that'd just held milk was used to serve him water.

He was a platinum blond and that may have had something to do with it. And yes, he regularly went barefoot in the snow while doing farm work.

I can take “Lactose Free” regular milk. Otherwise, cow’s milk gives me hemmoriods. A real pain....
