Perhaps I should have added a few smilies after the part where I wrote ........I did it many times (quit that is).at least a half dozen times, I never counted.
That last time it was not a conscious decision to quit.
It was more along the marvel of the sublime absurdity of turning around to go home to get cigs, already being late for w*rk, along the way having passed at least three places selling the stuff. Maybe not buying them along the way was just a manifestation of a genuine cheapskate.
I also am not telling anyone to do it my my way. YMMV. Maybe need a new acronym YMWV (your mileage will vary)? It was to show what happened in my case that resulted in finally quitting. Moral of the story aside. Maybe that one needed a cartoon character as well.
Hoping that the various stories will help the OP find a way/reason to quit.
DW quit a week before this past Christmas, after having part of her lung removed, along with a cancerous nodule. Fortunately it was stage 1A. Not many have that luck.
Hope you wife is doing fine!
I wish we could bottle "ah ha" moments.
