I was a smoker for a number if years. When I got married and when my wife was pregnant, every time that I lit up she would get sick - and throw up. Bad news in a car> Solution: she cut up long slices of CARROTS( celery does well). When I got the urge to smoke -I had a carrot slice - no I did not turn orange My colleagues at work started to call me BUGS! Yes, it worked.
