Kim; man-o-man !! I hear you !! I have quit smoking in the past...one time for 6 months. I never smoked when I was PG, but I never considered that "quitting"...I was just stopping until the baby was born !!
My main triggers now are also boredom and stress...two opposites for sure !! I remember when I had quit in the past, and finally gave in to the urge, and bought that pack of smokes and felt totally defeated. The smokes won !! Gosh, I hate that feeling.
I am really trying to hate every cig I smoke right now...telling myself I am stronger than the crap and chemicals they put in these things....that they can't control me anymore !! It's become my mantra.
I plan to quit mid-week, next week. Hopefully by then, I will have a mind-set that will make me feel good, and proud of myself when I wake up to a day with NO SMOKES...anger is a destructive emotion...but channeling it in a certain direction can be useful !!
Good luck to you !!!
