Strong smells will instantly give me breathing problems. I used to sit next to an older lady at an old job that used to pour a bottle of perfume on every morning. My face would start swelling the minute she walked in the door. Same thing with cigarette smoke. I was soooo happy when she retired. I went to my next job and had to share an office with a heavy smoker. I threatened to quit, so they moved me to another office. That worked, but then I had to start working with the nutty receptionist who wore heavy perfume and smoked. I feel so good now that I'm at a new place. No perfume wearers or smokers! I finally got my sense of smell and taste back.
