Heres the steps I would suggest as I was a smoker for 20 years. First use the strongest patch you can buy and chew the hell outta some gum. It does work. Second follow the steps from the strongest patch to the weakest. ANY INHIBITORS QUIT. Example for me was coffee, soda, alcohol. Now if you are a drinker buy the "Ecigerettes" they really help a lot, but not initially. Get used to the patch for at least a month before you go to the Ecigs, I prefer the "Blu cigs" they're strong and have a good taste to them. Oh the last step, MAKE YOURSELF DO THIS. I promise you will "look" better, feel wonderful and now you can live a lot longer.
Go "cold turkey". One's body will excrete the nicotine within 48 - 72 hours of cessation of the habit. How much one smokes is called tolerance. The urge to smoke is the addiction which is mental, between the ears. Give yourself twenty - one days to form a new healthy habit. Each day without a cigarette will create a stronger mindset on which to build upon. Doable. Used to smoke 2 - 3 packs a day, way back in the past. Safe Journey
Go run around your block then try to breathe out from a straw. Now try that with a coffee straw. Once you have the feel of that. Go look up COPD. Stop while you're still able to breathe n do your normal activities. Remember your lung cannot regenerate itself once its damage. Wheezing is not a pleasant sound. I know it's hard but slowly knock off the habit before you regret it.
