Why is it that I went for almost a week without too much trouble and now, 14 days into my SmokeStop programme, I'm desperate for a cigarette?
I know I can't have one, but the craving is back. I'm entering the dreaded Danger Zone. I have never overcome this stage before. For the sake of my health, and bank balance, I've got to - this time.
I'm telling myself to stick with it. It's that tiny, tiny part of me, the bit that's screaming "One puff won't do any harm", that could be my downfall.
It's going to be tough over the next day or two.
