Meat eaters. What's preventing you becoming a vegetarian/vegan ?

I was involved with a man who did all our meal planning and cooking. At one point he decided to go vegan with our meals without telling me. I ended up so cold I had on sweats layered over a t-shirt and had two blankets over me trying to get warm. I told him I needed protein so he went and bought some fish and cooked it. Within an hour after eating the fish I was warm enough to get rid is the blankets and sweats. Vegan just doesn’t work for everyone. And I am one of them.
