It's not so rare in my experience. I was deeply into the vegan scene in Santa Cruz CA with a crowd of quite committed people. Perhaps excessively so. Very clean, mostly raw diets. Several good friends dropped out for health issues like brain fog, cold sensitivity, heart palpitations. Others did quite well. I only know of one who is still vegan two decades later but there are probably others. And of course people who start down such a path are liable to have pre existing conditions. But it's sad to see the people that it isn't working for stay with it for too long out of a sense of shame or a need for community. I wish it were less a matter of identity.
