From above: With so many people now getting over the one week mark and the reality starts setting in, some people find themselves in amazement that after numerous quit attempts in their life they finally pulled it off. Also, some people who have quit before for significant periods of time only to have relapses start to get apprehensive as to will this one stick or follow the course of the past quits.
There is something different this time that gives you all the advantage of being able to succeed over the long haul. The difference is the understanding of drug addiction. If you know and equally important continue to believe that you were and are still a recovering nicotine addict and that one puff is going to undo everything you have accomplished, this quit will last. If you ever allow yourself to fall back to the mindset that you are off so long, like not smoking so much, or alternatively hate smoking so much, feel so good, and it seems so easy that you start to think you have it totally under control, you are no longer an addict and so if you have just one or two cigarettes or even puffs, this quit will go the route of the others. But if you keep remembering you are a recovering addict, even though there is no visible sign and for the most part the addiction is asymptomatic, as long as you keep recognizing it is there and has the potential of taking you down with any little infraction, well as long as you continue to understand that premise this will be the last quit you will ever have to do.
Stay focused on what you have accomplished here. I know I saw from some posts how family members are still making a big deal out of your quit, but that is going to subside soon. Family and friends are going to start to take it for granted that you just don't smoke anymore and that it is no longer a big deal. But your not smoking is still a big deal and should remain so for the rest of your life. Not to others though but you each and every one of you. To keep it a big deal, wake up every day and say you are not going to smoke that day and congratulate yourself at the end of each day for accomplishing that designated goal.
Day by day, stick to the goal. Every day is another victory worth celebration that over time will become weeks, months, years and decades worth celebrating. All these landmark times will become a reality for each of you as long as you never take another puff!
