When I was quit for 9 months, I could not say that I would never smoke again. After living through the Navy Yard shootings last year and walking through my boss's brains and blood, I smoked. For one week I smoked. I analyzed each and every puff I took because I wanted to see if what Allen Carr had been saying was really true, that we get nothing from smoking and never enjoyed it in the first place. So, from that first cigarette to the 20th, not one puff did I enjoy. Not one cigarette calmed my nerves or took away the pain, hurt or anger. They did nothing for me. Allen Carr was right all along and I had to be bull-headed about it and learn the hard way.
Once I put that last cigarette out at work, I knew that I would never smoke again. It's because I know and fully believe that it does nothing for me. At one time I thought it did, but now I know better.
I think some other addictions are different because you actually get enjoyment out of alcohol etc. and it's fun. There is no enjoyment in smoking cigarettes and it's far from being fun. Allen Carr told me and it took a relapse during a very shitty time in my life to understand what it was he was saying.
You're right, there is no "one size fits all" approach when it come to quitting but there is one fundamental truth that must be learned if one is going to quit and stay quit without feeling like they've given something up or are somehow missing out on something by not smoking. That one thing is to remove the desire to smoke by understanding and believing that the cigarette has nothing to offer and you never enjoyed smoking in the first place.
Now as far as the white robe, we have a man here that wears a kilt and even runs in that kilt. :) What ever clothing you choose, if it doesn't have pant legs, remember to hold it down when the wind blows. :)
