Grats to you James. Even if you fall back for whatever reason no worries. My motto is, not having one analogue is good, more better and the goal is none. Just remember this is not a diet where you can undo a lot of hard work by falling back into the old pattern. If you do, figure it out and and move on, if you can't we're here to help. Should be little to no stress stopping smoking this way, also plenty of folks still have a few here and there and that's fine too. I always amaze myself remembering back to what I used to do and how I planned things around having or getting a pack of cigs, and the stress involved when those plans fell apart.
