Hello evilcan,
I remember being scared that the cravings wouled go on forever like they did at first. Let me assure you that they will not. It actually calms down a lot more quickly than you might think.
One helpful tool here that I've used is the crave diary. I would highly recommend that you use it. It allows you to rate the degree of cravings on a 1-10 scale each day. In those first weeks, I was usually rating from 8-10. But it quickly tapered off into the 1-5 zone by the second month. After that, it dropped to 1's and 2's mostly. Then I started having some 0's, which means I didn't think about smoking for an entire day.
I still keep the crave diary for a couple of reasons:
1) It reminds me of how truly weak and infrequent my current "craves" really are (usually a 1 and it only happens 1 out of 4 days on average now). And by "1," I'm talking it's like a fleeting thought that passes after I take a deep breath. The rest of my days are 0's. Yes, I can go whole days without wanting to smoke now, and that is very nice.
2) Since it still pops up once or twice a week, I'm hoping to watch it continue to taper off.
Another thing to keep in mind is that you are in the process of extinguishing your triggers to smoke. Each time you resist an urge, it will get weaker. You resist the urge to smoke in the car, and I won't be so strong the next time you get into the car. You resist the urge to smoke on a break at work or school, and you will have less of an urge to smoke on break the next time. And so on. So, in effect, what's driving you nuts right now is going to give you a whole lot of relief very soon.
Hang in there. It will get better.
