Amertrine when I was pregnant with my first I would throw up from the smell of carrots being juiced in another room through a closed door. Now carrots had been a favorite vege previously, and I would not previously have said they even had a smell. Interestingly that pregnancy resulted in a child with an hysterical aversion to orange vegetables. And I took a long time to be able to eat them again myself, though I certainly can't smell them anymore (my husband and kids all can though I am sure, they have amazing sense of smell).
