In short: Try to change your environment in a way that makes it easier for you to quit. Avoid places with smokers and smokein general. Think about not smoking as often as you can. Make an affirmation that you won't smoke anymore. Than cut back. And finally just quit.
It's now the very best time to start your change. Stop smoking in 2010! I would wish you luck but you won't need it. Intead I wish you a successful and smoke-free new year!
