Hi wolfmother, and congratulations on getting through your first ten days.
Yes, it does get easier as time goes on. The quitting process includes learning how to manage yourself when faced with triggers. Triggers are events, feelings, locations, etc. that you associate with smoking. At the beginning of your quit, there will be many strong triggers. Each time you resist that urge to smoke, the trigger is weakened and/or extinguished, When a trigger gets extinguished, that event/ feeling/location/etc. won't make you want to smoke anymore. For instance, one of my triggers was driving my car. I had to learn how to drive my car with a cigarette. There were even parts of driving (sitting at stoplights, for instance) that were stronger triggers, since I had used cigarettes to deal with that situation for so long. But each time I drove somewhere without smoking, that association was a little bit weaker. Over time, it faded to nearly nothing. (I do still sometimes have an urge for a mint--one of my replacement behaviors-- at a particular turn on the way to work, though.)
Your husband really should go outside, as being in a house with cigarette smoke can be extremely triggering, especially early on. However, it is understandable that you might no be able to train him to change his ways at this point in time. However, do at least tell him that it hurts your chances at successfully staying quit, and that the people in your support group said so.
As for the emotional stuff...yeah. I went through a lot of moodiness in that first year. I'd have thee very ragey-like emotions over little stuff. I'd know that my feelings were completely unreasonable and out of proportion to the situation, but that didn't do anything to change them. What I learned to do was to accept the feelings without acting on them. Deep breathing can be very helpful with that. Just breathe calmly and deeply, while noticing how your body feels physically. You will most likely notice that your feelings are changing as you breathe, creating various physical sensations and thoughts. If you just sit and watch it, instead of fighting it, the feeling will often move on by itself. Another helpful habit is to start exercising. If you're angry, go take a walk. You will feel better, even after a short one.
Again, congratulations on you quit, and welcome to the boards. Please keep us posted on your progress.
Usually it's because they were not really prepared for the quit. Resentment and being over emotional is NORMAL during a quit. Don't worry about it. You'll learn to adapt to the "new you" soon. There's a lot of other emotions you're going to have to learn to deal with too, but you can do it. Hey, you've been smoke free for going on two weeks now. If you can do that, you can do anything if you put your mind to it.
