i agree with most of this. i would add, try quitting 1 day before the start of a three day weekend. almost every smoker can go one day without smoking. by that time the weekend comes and you have three days to de-stress. when i smoked, if i tried to quit during the work week, i would get stressed or irritable at work and then want to smoke. after a three day weekend and four days of not smoking, the stress is more manageable without getting irritated.
