Original sentence: Allen Carr (born 2 September 1934), who until 1983 was a chain smoker himself, is most notable as the author of books on how to stop smoking and, as he stresses, escape nicotine addiction.Carr claims that, contrary to their perception, smokers do not receive a boost from smoking a cigarette: smoking only relieves the withdrawal symptoms from the previous cigarette, which in turn creates more withdrawl symptoms once it is finished; in this way the drug addiction perpetuates itself.He further asserts that smoking is less addictive than is commonly assumed, that withdrawal symptoms are actually created by doubt in the mind of the ex-smoker, and that stopping smoking is not as traumatic as is commonly assumed if that doubt can be circumvented
Edited sentence: A comparatively large group of people have gone public and declared that, after many unsuccessful attempts, it was Carr's book that helped them to stop smoking.Allen Carr (born 2 September 1934) is most notable as the author of books on how to stop smoking and, as he stresses, escape nicotine addiction.Carr points out that, contrary to their perception, smokers do not receive a boost from smoking a cigarette.He further asserts that smoking is less addictive than is commonly assumed, and that the withdrawal symptoms are in fact simply doubt in the mind of the ex-smoker.In this way the drug addiction perpetuates itself.Many readers appreciate the fact that Carr, who until 1983 was a chain smoker himself, explicitly allows them to carry on smoking while reading the book.Smoking a cigarette only relieves the withdrawal symptoms from the previous cigarette; the withdrawal symptoms arising from the current cigarette will be the prompt for the next.Stopping smoking is not as traumatic as commonly assumed if that doubt can be circumvented.The claimed success rate for those using Carr's method is about 70-90%
