Focus on the good feeling of NOT smoking.
It helped me look at the positives of not doing it than think about the negatives of not!
Like.. Lets see, stressful situation and I'd be looking for a smoke; but I can't have one, so I'm focusing on my ability to deal with the situation head-on instead of running away from it. In the end the situation resolves itself because I acted on it properly.
Then; the feeling of healthiness, ability to BREATHE is amazing. I never quite realised how restricted my breathing was when I smoked. After I had some the other day after not smoking for a month, it felt like someone tied a rope around my lungs and I couldn't talk, laugh, breathe properly the next few days. Hell, I'm not touching another one EVER no matter how drunk I get.
Then you can also think about the positivity of NOT smelling like an ash tray. Much more pleasant for you, and for others around you! I mean after about a week of not smoking, don't those smokers on the corner smell awful?
Focus on that.
Keep going, it's worth it not to smoke, for your future, and for the future of the ones around you. Well done on your progress!
