Certainly, prayers on the way...I was an on/off smoker for about 10 years; I finally gave them up for good over 4 years ago - it's tough, but it sounds like you're already through the hardest part. I found that, once you got through the first 72 hours or so, it got a lot better. Eventually, the cravings will subside.
Every once in a great while, I get a craving, but it usually doesn't last long. Just think of all the money you'll save, that you can spend on flies, rods, etc.
