For all you quitters, from a quitter: folks who study addiction have more than once stated that, once established, nicotine is as firmly fixed an addiction as heroin and as hard to quit. Is it reasonable to expect anything that tough to be accomplished the fiirst time you tackle it? So don't beat yourself up for slipping (if you do). Just put that attempt down as training for the BigOne and plan the next.
It may make it even harder on the really tough, first few days, if tell yourself you're never going to have another puff, and it made it easier for me just to think that I was only postponing that next ciggie—like you learned you could do when your workplace went smoke-free. Remind yourself you can do that. Only now you'll postpone right thru a coffee break, or right past that first beer after work.
Remember, you're teaching yourself a new set of habits, and a good teacher encourages by focussing on the student's first small successes—likecorena's software does. And you will have some success every day you try. Stay with the success, not the failure.
After twenty years, I still have the odd moment where I think how good a Gitane would taste. But now I think of it like looking at a picture from a long ago holiday. Luck and success to all.
