I used Alan Carr's book amongst trying all sorts of things and even though I did not stop immediately, I used one main thing out of his book to help me. Whenever I craved a ciggy I would mentally ask myself 'is having this ciggy going to make me feel better/make that problem go away? The answer was nearly always no, so I would refrain most of the time. Don't beat yourself up if you have the occasional blip, just don't let the blip turn into a full on smoking day. The other thing I found, although I didn't mind the smell of people smoking near me, the smell of 'stale' smoke turned my stomach and then I would think 'oh my, did I used to smell like that?', which was quite a wake up call. Apologies to any smokers, but it's not until you give up, that you realise how bad them smell can be! Good luck xx
