Allen Carr has died.
Allen Carr, 72, quit his 100-a-day habit 23 years ago, before going on to become a millionaire by advising people on how to stop smoking.
His books, about the Easyway method, have become international bestsellers and he ran clinics all over the world.
When he was diagnosed with the disease, Mr Carr said he saw his illness as a way to encourage more people to quit.
Talking at the time of his diagnosis, Mr Carr said: "Since I stopped smoking more than 23 years ago I have been the happiest man in the world. I still feel the same way."
Me too Mr Carr.
This man is the reason I don't smoke today. I went from a thirty a day habit to none overnight having read his Easyway for Women to stop smoking nearly four years ago. I never touched another cigarette since. I didn't even finish out the pack I had. Incredible, especially as I LIKED smoking-or so I told myself.
Sorry to see him go and I am eternally in his debt.
Go n'eiri an botháir leat.
