I think it is different for every person Flench. It is also about motivation, to some degree. My motivation? One day I went to buy a carton of cigs, back when they were $25, or so. I plopped them on the counter and the clerk rings them up,......$50!
I had to look dumbfounded and she explained a new tax went into effect. I looked down at the carton, slowly pushed it away and never looked back. The rebel in me would not allow myself to be extorted into paying some sin tax. Then I discovered I had no side effects at all. I kept waiting for it. It never happened. It pissed me off!
All that wasted money.
Now, there is one thing. Maybe this is it. I had smoked myself down to Merit's lightest cig. The lowest nic and tar one they make (Ultima?). I was smoking them for a few years. Maybe that had something to do with it.
