Good luck. 3 years smoke-free here and no intention of going back. What worked for me was basically will power, no fancy gadgets or schemes. And if I can do it, anyone can! I just decided one night in the pub that I was going to give up. Think I had 3 fags left in the packet when I got home and rather than chuck 'em away (why add to the pressure of giving up and make it harder for yourself?? Anyway, they were paid for!) I smoked them the next morning, when I felt like it. No pressure. Then I decided not to buy another packet. For every reason that then entered my head as to why I wanted a smoke, I would counter it with logic. For example, if I thought I needed a fag to reduce stress, I would point out to myself that in fact, smoking is proven to increase stress levels. Furthermore, I told myself that I coped for many years without ciggies, so I didn't need them now. Just simple stuff like that. Realising and convincing myself that I only wanted a fag because I was addicted and not because I needed them was pivotal for me I think. Don't get me wrong, it was difficult for a couple of weeks but the crux came at a mate's barbeque where the drink was flowing. I told myself that if I could get hammered and not smoke, I'd won. I managed not to, despite temptation, and that, I think, was it - I was a non-smoker. No more cravings, no more missing a smoke. Food tasted better, clothes didn't stink anymore, hangovers were less painful, I had more money in my pocket and soon felt fitter. Being an active mountain biker/runner/hill walker I noticed fitness improvements very quickly.
Things I learnt, which helped me enormously:
1. You have to want to give up, not just do it because you think you should (tried that, failed every time)
2. Don't put undue pressure on yourself by imposing unrealistic/unachievable goals. If you really really really really want a fag, have one. Then give up again the next day.
3. You do not need to smoke, no matter what you think - you never ever need to smoke a cigarette
4. Everything is better when you don't smoke
4. More money in your pocket = more camera stuff
Apologies if I've gone on a bit, but I hope this helps someone somewhere at least!
