Getting nauseous when eating meat?

I was eating some chicken for dinner when I suddenly felt like gagging, and it was the thought of having it in my mouth that made me feel sick.

Sometimes, but not always, I’ll get stricken with intense nausea and loss of appetite when eating any kinds of meat, even though I love it.

Is this known as any thing? And do some vegans/vegetarians go through the same thing before they quit eating it?
