Mood-elevating drugs might be helpful in this regard. Each time you get an urge to smoke, redirect and mask it. Only then do I return back to whatever I was doing. Fortunately you will not experience the desire to smoke during the middle of sexual relations, but you may have to take a walk afterwards. The walking is diversionary and punitive to the smoking urge and helps to decondition it.
Walks are punitive as they often are inconvenient and aggravating, and disrupt other pursuits.
The walks are good exercise and will help you avoid gaining the weight that smoking cessation entails. These walks become more brief and less frequent over time. If you start your cessation program with a vacation, much of your walking will have already been done by the time you return to work. Thus, you might be able to arrange for walks at your job, arguing that the time spent in these walks, will, over time, be less than the time spent in smoking breaks. When you are unable to walk, try plan B. Monitor your smoking urges.
