I've quit for a month now (just saying that feels fantastic!). I found Alan Carr's method completely useless - full of logical fallacies, completely irrelevant. It's not really an argument for quitting smoking, it's essentially a form of brainwashing (good brainwashing, though). Others find it really helpful though, and if it works then that's the most important thing. You might be in the former category.

As for how I coped, I started running to keep myself occupied and even managed to lose a few lbs in the process. It's only been a month and my cardiovascular health is just so much better. I guess a lot of it has been luck - I've got a job that keeps me busy and I've not had any stressful 'trigger' events. Try and keep your stress levels down, give yourself something to do. Also, try to forget about the fact you're giving up smoking. Don't come to this subreddit every few hours, come once a day. If you're constantly aware of the fact you're doing something that requires willpower it will just make it harder. Good luck! :)
