I am glad to hear that it's getting a bit easier for you G. Give that some thought, and remember how far you've come already if you ever feel like picking up a butt. Not to mention how long you'd have to go through this agony all over again one day if you start and then quit again. I hope I'm not sounding condescending, and granted it's small consolation at this point, but I am sure you'll find that it will continue getting easier and easier as time goes by.
I am not around too many smokers myself, so I don't really think about it much if at all anymore. About the only time I really do think about it is when I see or smell someone hammering a nail. As far as missing it goes, it's quite understandable that you'd miss it for since it's been part of your daily routine for such a long time.
