There is only one secret to a forever quit. Decide not to smoke each and every day NO MATTER WHAT.
Smoking EVER – no matter what life throws at you - is optional. Understand that, as an addict, there is never going to be such a thing as “just one” for you. You can always decide not to give up on your quit. You never have to go through Day One again. It's ALL up to you!
What ELSE can you do?
Go for a walk
Call a friend
Come to the site and read
Play a computer game
Blog “HELP” here and wait for us to talk you off the ledge
Go for another walk
Do a few toe touches or wall push-ups
Take slow/deep breaths, starting with this and going slower and deeper as you repeat
