The vaccine for quit smoking is NOPE !
I learnt long way .. During earlier quits, one puff or one cigarette was culprit, used to bring back to addiction. After my quit on 26th November 2013, decided what ever happens NOPE means NOPE.
My few friends who could join the freedom from smoke journey around me, and who did not follow NOPE are again trying to quit the addiction.
Those who are already on freedom from smoking journey, would agree that NOPE is vaccine in our hand (and mind) !
Thanks for this community and wonderful site those have reiterated many times the importance of NOPE !
All the best !
