Back in the day, when people had pernicious anemia, they gave them raw liver to eat, instead of B12.
When people were Celiacs, they had terrible diets, eating a lot of bananas and such.
It's a lot better for allergy sufferers these days. I'm sorry that you had to go so long before you found out about your problem.
How is Erin doing?
