Right, you all seem to have re-focused so concentrate on what ever primary reason you have to be an ex-smoker.
Willow it's your ds and his loathing of it, fg you know your running will improve if you keep off it, each of you have got something to focus on.
Write yourself a big sign 'I am not going to smoke because it makes me feel cr&p , my ds hates it, I want to save ££££, I hate the stench etc etc you get the drift, and stick it somewhere really obvious.
Every hour or 3 depending on how bad you are feeling, stick a tick on your chart (yes a grown-ups star chart !) and collect them, after all, the money you are saving you're not used to having yet (it normally goes up in smoke !!) so spend it on something frivolous or extravagent for YOU.
Think of some of the other positives, you'll save on face cream - smokers skin is AWFUL, no more yellow nails, your eyes won't be so puffy, your hair won't stink. You might have a yucky cough for a while, I did but that was just my lungs ditching all the crap.
BUT everytime you feel better about not smoking and get the feeling that you've proved it's possible so it's ok to have one now I've beaten it you must come back here instead because that's just an evil trick that nicotine plays, often after a week and certainly after 4 and again at around 3 months IME.
No excuses girls, there is never a good time to quit.
