That sounds like it was a tough day and overall kind of a bummer. But the bottom line is that YOU DIDN'T SMOKE. It might have felt like a bit of a hollow victory at the time, but for me on those kinds of days I would often end up retroactively pleased for myself once I had the gift of a bit of hindsight. It IS a victory to make it through those bummer days when quitting doesn't feel good or easy. To stick it out even on a day when the rewards feel low - that's a true win.
Facing those less common smoking triggers will get easier with time. By the time I had a good solid foundation of quitting underneath me, I would still occasionally be surprised by the uncommon situations that would make me crave a smoke out of the blue. But one by one, each one would roll around, and I would not smoke, and then I would have a new precedent to work from. I actually found some of those uncommon triggers to be tougher, because I was not mentally prepared for them to pop up and so my defenses would be lower. The usual suspects (driving, waiting, meal times, first one in the morning, etc) were expected and so I would show up armed, so to speak. The surprise triggers were a little scarier because I would have to do some unexpected on-the-spot mental work to dismiss the cravings. Again, labelling it helped for me: "Hmmm, interesting, here's a smoking time I totally forgot about. My brain is letting me know that I used to grab a smoke after a doctor's appointment ... Well, now I don't do that." These little self-talks coupled with intentional deep breaths to calm the central nervous system were really effective for me. It is now SUPER rare for me to surprised by any smoking-related thought. All those situations eventually roll on up, and then roll on through. Just keep it going.
