The thing is Eddie, you can't stop someone smoking. If that's what your wife wants to do then she'll do it. At the most, she might tell you she's quit but continue behind your back for a quiet life. Some people find it easy but others just can't do it. A colleague's husband had his larynx removed due to throat cancer and she said there were others who had had the same op and were standing outside the hospital smoking through the holes in their necks. Nagging her about it won't achieve anything - it may be more likely to make her light up in fact. I sympathise with you, but it's her choice, and while she will know how much it upsets you and what it's doing to her health, if she can't quit she can't quit. Has she tried the electric cigarettes though? It's supposedly still like smoking and she will still be getting her fix of nicotine, but without all the other stuff. Might be worth a try.
