I recently started eating meat after 22 years of vegetarianism. I had some mild nausea the first couple days, but it passed. I'm not sure how much of that is real and how much is pyschosomatic. It was definitely a freaky experience for me.
I have, however, had TWO back-to-back, persistent low-grade colds since I started eating meat about a month ago, after many months of nary a sniffle. I'm beginning to wonder if I'm not having some sort of allergic reaction as my body adjusts, or if it has somehow affected my immune system. Whatever it is, it's pissing me off.
