I never read the Allan Carr book, but it sounds about right. I kicked my 60-80 a day habit 16 years ago going 'cold turkey'. It was very difficult for the first week, but each week thereafter got progressively easier. My friend and colleague who stopped a few weeks later using 'gum' now uses 2 packs of Nicorette a day. I hope he doesn't contract cancer of the throat or mouth like so many of those Scandinavian nicotine 'teabag' munchers. Why use a product of the tobacco industry to try to stop smoking?
My personal feeling is that using one drug to kick another is a big mistake. I speak as an alcoholic who kicked alcohol 16 years ago too without drugs or special treatment.
