Welcome to Freedom ZenForce! You have made such an impactful decision for your health and future. The more you read and watch, the more educated you become, the more grateful you will be that you are ridding yourself of this awful addiction. Your words insidious addiciton is such a good way to describe it. 
Also, those moments of finding a trigger after a job well done, or after a problem resolved are so common. Read and watch everything Joel and the staff post for you. 
Also there is a thread called something like, reminders from the executive assistant, I love that one. The eBooks are also good to read. And I also like the positive rewards of reading the 'benefits timetable.'   
Like you I was a long-time smoker. I had 'quit' hundreds and probably thousands of times, like a yo-yo dieter, every monday was going to be the start of a new quit. My mindset was just keep trying until one 'sticks' 'I'm just going to keep trying and never give up'  But it wasn't my diligence of never giving up that got me to two years of freedom.....It was this site and the education here of the science behind how ever falling nicotine levels work, how stress causing you to excrete your nicotine faster and thus need to replenish your nicotine level, and what triggers are and how to face them, expect them and eventually the triggers fade away and you go that first day with no triggers or thoughts of using nicotine. It passes unnoticed. Then you realize, wow, I went a day...or two without thinking of it. Then the days of life without nicotine become your new normal. 
You can do this.
I used deep breathing to get past some of those false 'reward' moments and triggers. And like you noticed the smell on other smokers. My sense of smell returned to normal but felt like some superhuman strength. It's still mind-blowing how many things I missed smelling. Or missed out on all together. Everyone else would go for a walk, go do something and I would lagg behind so I could replenish my endlessly falling nicotine levels. 
You are doing great. Keep reading!
One would be too many and a thousand would never be enough!!!
One day at a time, keep nicotine on the outside
