Shannon, I can relate. I'm on day 9 and was at my quit day a few days ago and doubting myself in every way. I think if I were really patient, I wouldn't have needed the quick fix of cigarettes. Or, at least my brain wouldn't. For me at least, I find I'm becoming more patient and less irritable as I get more days smoke free. I know my addiction to nicotine at least contributed to it, because when I didn't have them and I started craving, I was so cranky and irritable. But, it's getting easier. I know my addiction to cigarettes and the routine I developed didn't happen overnight, so neither will my recovery process. But, I'm getting a little better every day and it feels awesome.
Trying to drive, make it through break at work, sitting in traffic, these were all things I told myself I couldn't tolerate at all without smoking. I was convinced, but then I realized I was believing my own BS, the little tricks my brain was playing on me. I was coming up with an excuse to smoke, any excuse-- it didn't matter. Finally, I had to get honest and admit that lots of people do the very same things every day I "couldn't" do without a cigarette, and they make it, and so could I. I could if I would. Everyone here can relate in some form or fashion to what you're going through, so post, keep coming back, and let us know how we can help.
As far as interest goes though, I think you get what you give to it. I'm trying my darnest to make it work now. Not so much the last time I tried to quit, so this time I've tried giving it serious time and thought each day. Which, brings me to the fiance thing. My fiance is a smoker and he wants to quit but isn't there yet. If he doesn't, sure I'll wish more for him, that he could, but ultimately I am quitting for me and if he quits it will be for him. He's going to love me whether I quit or not, he loved me when I was smoking. But, I've never seen him look more worried than the night I couldn't hardly breath and he thought he was going to have to take me to the hospital for my asthma. So, I wised up and realized I was hurting and so was he. He'll love me either way, but I'll love me more if I treat myself well. You can do this, if you put your mind to it and stay focused. Let me know if you need encouragement or a friend to voice your concerns to. Good luck Shannon!
