This issue is a tricky one. Many people that used the cold turkey method advocate that avoiding as much as possible situations that you used to smoke should be a priority, others advocate that you should not do that because you need to start retraining yourself to live without smoking from day one of your quit.
Both views and opinions are respected, and both stem out from the ex-smokers personal experiences and ordeals.
Personally, I am somewhat in between those two views. I do think that you should stay away from a situation that you used to smoke as much as possible especially the first three days where physiological urges are still in place. After those three days, I agree with the second way of thinking that you should just continue living your life retraining your mind to live without a cigarette and proving to yourself that it’s possible and very much doable to have a smoke-free, healthy and happy life.
It’s a choice, for example, if when you were a smoker, you used to go out to the porch of your house or your workplace and smoked with other people. Now do not go out when the other people smoke, talk with the non-smokers indoors or wait for the smokers to finish their smoking and speak with them when they come inside.
