I get this way (after being Vegan for 6 months) with chicken and beef. It's wierd becasue I hated pork all my life, but it still just smells like "ew pork" and not totally gone bad like cow and chicken does to me.
Mayonnaise, sour cream and cheeses ESPECIALLY smell disgusting to me to the point that I can't be around them, especially melted cheese. ...ew. I have to make sandwiches as a small part of my work (blah retail) and I always ask- every day- if the chicken salad is bad, or the cheese is bad, because it smells so sour to me. Gr.
