First I'd like to congratulate you on your decision to quit smoking! What a challenge that will be but YOU CAN DO IT!!
June 16th I celebrated 13 years of being a non-smoker! I still celebrate the day (even if just to say to myself ~ good going Rose!) Anyway, for me the first 2 weeks were the absolute worst! I did take it day by day though. I'd wake up in the morning & say "today I will not smoke but if I really HAVE too, I will have one tomorrow!" Then the next day I'd say it again.
My Mother tells me that I was very difficult to live with those first 2 weeks but we managed! As another poster mentioned, I also smoked menthol ciggarettes so I sucked down a lot of Altoid Mints during the withdrawl timeframe. That helped but what also helped was changing my habits. Like if I smoked more when I was on the phone (which I smoked constantly while on the phone), I gave up talking on the phone. I always had one with a cup of coffee ~ I cut down on coffee. The other most fave smoke was after a meal...that one was the hardest to overcome. So immediately after a meal, I began walking! I mean I'd dump my plate in the sink & take off! But all those behavior modifications helped me.
I am totally offended by the smell of smoke while indoors but if I am walking to the mall entrance & someone is smoking & I get a drift of that smoke ~ it smells heavenly to me! Not "heavenly" enough that I'd start up smoking again though!
Lots of luck & do whatever you have too, to not go back to smoking. It will kill you. An Aunt of mine died of throat cancer. I can't even begin to tell you how much she suffered.
Stay strong, you can do it!
