This friend told me about this book by Alan Carr that he had read and after reading that book he quit. I laughed at him for like 5 mins, called him gullible and said he had a weak mind. Then one day months later I stumbled upon this series of videos by him about quitting, lazily watched it part by part (I think there were 4) and after every 20-30 mins the video would ask me to smoke a cigarette. I happily did. Then as it came to an end it said go ahead smoke your part cigarette and I was like Wtf?! It was genuinely quite scary but that was the last cigarette I smoked. Didn't believe me try it out, ive won this bet a few times after that myself. ALAN CARR. Check it out!
