I lost my quit a couple of weeks ago, smoked all day every day for six days and then managed to stop again. So here I am back on day six. I just couldn't relax and enjoy smoking again because I knew I'd end up having to quit again sooner or later. I decided to make it sooner in the hopes of avoiding having to go through the awful withdrawals. It's been pretty easy so far. Nowhere near as bad as when I first quit back in January. I know I've had a narrow escape. I could so easily have got sucked back into the abyss....
If you're thinking of smoking just one... DON'T. It's not worth it.
