<<Disclaimer: Verify this information before applying it to your situation.>> I am a bit confused about mayo and mustard. Hellman's makes me VERY sick within 8 hours and French's isn't much better. Am I extra-sensitive to the ingredients? I always suspect when a product lists 'artificial in- gredients'. I take those as non-specific and avoid them. There is a 'hot' mustard (I don't really like it) that seems to have no bad effects. Any wisdom here? Lissy
