That's great LT - you are dealing with the daily routine stuff and the old brain is being reprogrammed on a daily basis. That's crucial for long-term success!
It's unusual incidents like meeting your old friend that will continue to trigger for some time, plus annual events like Christmas, birthdays, anniversaries, vacations, season changes, et cetera. Once round the sun should do it but always be aware!
Forewarned is forearmed! Nothing out of left-field wanted here!!
I think this finally clicked for me this past Monday. I had my first trigger without a crave, and I just sort of experienced it, thought "huh, that's kinda weird," and kept on doing what I was doing.
At this point I have gotten past most of my triggers because I've gone 50+ days without smoking, all of my daily routine stuff I can do without thinking about smoking anymore, so mostly I just have the occasional mental craves to get through. But on Monday I went to see a friend I hadn't seen in 4 months, since before I quit, and it was such a bizarre feeling to have, like "I feel like something's missing, maybe a cigarette? hmmm..." And it felt so great to not actually want one!
