I must be totally out of my trolley... I had cancer of the tongue two years ago and had parts of my neck removed along with the floor of my mouth and 3/4 of my tongue. I started smoking again 5 months after the op due to major distress having to eat through a tube directly into my stomach. I still havent given up and no doubt will regret it even more one day!... You would think that I would have learned a lesson! My advice.... If you havent started... DONT!!!... if you have... either cut down or try to give up!
