Oh, well done to you all! Stick with it, it really does get easier and easier - and as time passes, the thought that you would ruin the achievement you've accumulated if you weakened really helps, at least that's what I found. I wonder if there's something about the 'cyclist' determination mindset that helps with this?
Anyway, every year I mark on the calendar the anniversary of my last day as a smoker - and it's 15 years tomorrow!
At £5 a day, say, that's £27,300 I've saved!
(And yet I still occasionally have that awful dream where, oh no!, I lit a cigarette!!)
