We've been researching how to help people cope with the cravings that come with quitting. It's really important that you try to change your every day routines, so you don't get 'triggered' to smoke by all the associations in the environment. So do try sitting in a different seat, reading a different newspaper, swapping coffee or tea for juice, hanging out with new people, a shower instead of a bath...anything that's not your normal routine. This will help your brain to create new pathways and links that aren't hooked up to your old smoking habit. This Do Something Different method is particularly helpful for people who feel they can't reply on willpower. I've written more about it in a book called Love Not Smoking, with Professor Ben Fletcher (but this isn't a book plug, just a genuinely useful tip I wanted to pass on). Good luck!
