If you want to quite you've really got to "Want" to quit. If you don't then you will fail - simple as. As to the method you choose, that is up to you. Me and the wife decided on "Cold Turkey" and we stopped at the same time. This also had the advantage that neither of us wanted to be seen as weak to the other - so we kept each other going. I'm pleased to say it was a total success. We both threw away all of our remaining cigarettes one Saturday evening and here we are 5 years later and haven't smoked since.
