I remember when I was quitting I finally got to the point one day where I was around some smokers and the thought that I had was one of feeling sorry for them. Sorry for them because they just HAD to have their smoke and I no longer did. What a great moment of Freedom I experienced that day.
You know @Genecanuck, quitting smoking is mostly a mind game we have to play with ourselves. We often have to force ourselves to focus on not smoking when around others who smoke because our subconscious makes us think we're missing out on something wonderful whereas the reality is you are missing out on nothing! You are building a new & better life for yourself.
Sounds like you're doing great in following the right path here. It's not always easy, especially in the beginning but very well worth it in the long run! When you find yourself in those situations (around other smokers) try forcing your mind to look at what they are doing not as something you're missing out on but take pride in yourself for being able to reject what your addict mind is trying to make you think of the situation.
You are progressing to a much better life while they are stuck with being ruled by their addiction! You're the winner in that senario
