Hi yts.,
I would not stress too much about the 3 month point.....all this, (a relapse point) can happen to anyone at any time. Nothing miraculous will happen at 3 months or after that. You will continue with your quit happy in the knowledge that you have coping mechanisms in place for whatever the Nicodemon throws at you. Yes, we all had the odd urge to smoke, and there are lots of triggers, but, as I say, if you have the coping strategies ready, you will win.
My worst one was after 9 months, when the water tank in our house in Italy leaked all over the basement floor. I was VERY stressed, but the only time I had the urge for a cig. was hours after the clear up, when I was in reward mode, so I went upstairs and had a relaxing bubble bath as a reward instead. The answer is, "Be Prepared"
Whatever it takes, just don't smoke!
Love Lolly.
