I changed 5 years ago too. I had to use some reverse psychology to do it however. A good customer told me a 'truism' - "You do not 'quit' smoking. Because quitting means nothing will take it's place, and you will feel that void in your life and resume your habit. What you need to do is to change. Change from being a smoker to becoming a non-smoker. You effect change in your life by substituting a bad habit with a good habit. All you need to do now is decide what you like and don't like about smoking and make that change."
So, that's what I did. I first had to determine what I liked about smoking and what I didn't like. I liked the draw on the cigarette, the inhaling, the exhaling, but only when I felt well. More and more it bothered me, my lungs feeling raw, sometimes it hurt. What I did not like about it was the dependency (I would drive 10 miles to get a pack of cigarettes vs. running low and forcing to ration them, and running out was inconceivable) and the smoker's cough, always clearing my throat, disappearing at games or movies or functions to 'go have a cig'. So, I had to come up with a plan of action that would force me to change. What cigarettes did I like? Full Flavor. They could be throat rippers, didn't matter as long as you got your money's worth. OK, so take baby steps. Buy a carton of lights, see what ya think. Well, tasted like crap, but semi-ok. Next month make the commitment to change again. Ultra lights. YUK! Of course, and I knew this beforehand, the body will adjust. Second month doing the ultra lights and they were like sucking on straws. So the third month.. pick up the pace. Now, go outside and have two instead of one. Every time. I was ingesting more smoke, but I was paying for it. More and more coughing. Hacking. Almost throwing up at times. Then do three instead of one. Now we're getting somewhere! I'd set the date when to change - in about a month, Christmas Day. Why? The other leg of my plan. Forced incentive. This is when GPS's started coming out. The second year and prices dropped from $900 to $500.
Now, we have many doctor and cancer bills, strapped tight as always. Inconceivable to spend more than $50 for Christmas. But.. we're talking a life-changing event here. Big challenge, big risk. So I resurrect my store card and buy a GPS on credit - $550 including case, screen protectors and 2 year service plan, and give it to my wife on Christmas day, right in front of my two sons who could never believe I could ever stop smoking. But, I was determined to replace smoking with non-smoking and a financial commitment was the final kicker. The GPS was $50 a month at 0% interest for a year, my smoking cost $85 - $100 a month. I was committed, both to my sons and my wife. Plus, as a caveat, I'd asked for bags and bags of sugar - free candies for Christmas as I was diabetic. At 11:15am 12/25/2005 I went outside at my son's house and smoked my last cigarette, my oldest loudly complaining that we still had one more present to unwrap way in back... it was the GPS that no one knew about. I told him it was necessary. Came back in, told the wife that I was changing from a smoker to a non-smoker, in front of the family threw away my cigarettes and lighters and explained how we would afford this giguntous gift! Of course no one believed me. I started eating those sugar-free candies and all I felt was relief! I didn't want to go back to smoking - I was ready to puke smoking so much! And have been a non-smoker ever since.
