I eat very little meat and go through periods where I can't eat it at all. I'll take a bite and spit it out- can't force it down my throat. It's an icky feeling. I think it's that you're becoming "lighter" and more sensitive to energy. I can only assume that the meat we eat has some pretty negative energy attached to it because surely the animal didn't enjoy being killed. I think that's at least what I'm sensing.
We're going totally vegetarian in our house after Christmas. I can't handle it anymore, either. In the meantime as I adjust the children to that I've been doing some reiki over the meat as I prepare meals. It seems to help.
