Alan Carr, ''Easy Way to Quit Smoking''.
paraphasing, ''smokers only smoke to get nicotine, they are fully aware of the possibilities for nasty early death but choose to carry on rather than quit because of their brainwashing that convinces them they need the next cigarette more than the possibility of lifeling cravings. Adverts only increase the schism between the truth and the brainwashing. In truth it is easy to quit when the brainwashing is removed, actual physical symptoms are no worse than a mild flu but usually less, overcome the mental issues first by reading the whole book right through''
Alan's book is an I ongoing bestseller translated into ten languages.
