I'll echo everyone else's comments by saying I also Love your post. It shows a real understanding of things. Being a smoker vs a quitter. The things you mentioned I believe will carry you through to your forever quit. Yes, things will continue to get easier for you. I expect you have realized it's a very slow process but it IS happening and will continue to do so. You're getting to the point where maintenance of your quit is key - just don't do anything silly on a whim and you'll be fine. You now know, smoking never solves anything so would we even entertain lighting up again?
I think I was at about 7 months when I just suddenly, out of the blue, had this epiphany about the whole smoking vs quitting thing when I started to feel sorry for others I saw smoking and glad about the fact I had quit and wasn't chained to my addiction any longer. That sort of moment will come to you as well I believe and in the very near future, if it hasn't already.
I'm 5 years in now and I'll admit, I have the occasional thought of ...."wouldn't a smoke go nice about now." Then I wonder; where'd that come from lol. Remnants of smoky memories I suppose but they are just fleeting thoughts; nothing more.
