I had stopped smoking many years ago. I had found the decision to be quite straightforward in my case.
Yet, for some reason, and in the face of stress I would sometimes 'wonder' how it would be to smoke a cigarette - simply to experience that pull, thinking that to experience this pull would give me relief.
A few months ago this led me to smoke a cigarette again. In the days after I had smoked this cigarette, I experienced discomfort within myself. I did not feel clear in my standing - until one evening as I was looking at this point, I realised that had to make an absolute decision on this point. The decision was that smoking is not for me and so there was no point in going there again.
After I had made this decision I was clear within myself and I have not experienced this craving again since.
