The other half decided that we were going to stop smoking together a few years ago, aside from a few minor slips I haven't gone back to it - she has, quite recently in fact, but that's another story.
The trick is to remember that you're not 'giving up' anything (that implies loss), but that you're 'stopping smoking'.
Good luck to all that embark upon this path, remember that all you need is yourself.
Nice positive thread too, well done
