Any urges for cigarettes that occur today are reactions to conditioned triggers. You are doing or experiencing something for the first time without smoking. It may be going to a bar, a wedding or going on a plane. It may be seeing a person or being in a place where you always had a cigarette in the past. It may be something you hear or even an old familiar aroma. The sense of smell is a powerful mechanism for triggering old emotional feelings.
So today, if you find yourself desiring a cigarette, look around you and see why at this particular time and place a cigarette is on your mind. Once you understand that the desire is being triggered by some reaction to an insignificant event, you can just say "no" to the cigarette without further problem. All you need to do is understand what triggered the thought. The urge will pass. The next time you encounter a similar situation you will not even think of a cigarette. You will have learned how to face another experience as a ex-smoker.
Quitting smoking is a learning experience. Every time you overcome an urge you will have overcome another obstacle that threatened your status as an ex-smoker. As time goes by, you will run out of obstacles and you can comfortably go through life a happier and healthier person. All you need to remember and practice to stay an ex-smoker is - NEVER TAKE ANOTHER PUFF.
