I went cold-turkey too. That was more ten years ago.
Yesterday I poured myself a cup of coffee and picked up the morning paper ... and found myself reaching for my shirt pocket where for thirty years and more there was always a pack of cigarettes and a lighter! It happens now and then.
I kept my cigarettes and lighter with me when I quit. I only tossed the cigarettes when I had been carrying them around for a month and realized that they would not be smokable anymore. But having them handy in the first few weeks seemed to make life easier.
My technique was not to quit, actually; I just deferred my next smoke.... from first-thing in the morning to my morning drive, to my first cup of coffee at the office, to coffee break that day, to lunchtime ...... and just kept on deferring. In a sense, I'm deferring still. But I claim to be a non-smoker anyway and my doc says my health risks are back to normal by now.
