Grats OP!!! Hang in there, it's worth it. I've tried several times in the past, and it does get harder and harder to quit every single time. My quitting attempts have lasted anywhere from a couple hours to 6 months, but I always come back to it (usually, out of sheer boredom brought on the banality of day to day life, not triggered by any traumatic event).
My most recent quitting effort started a month ago and it's going well so far. Relapses happen, just don't let them become a return to the habit.
Best motivation I ever saw actually came from a friend who got some information from a hypnotist (yes, it sounds ridiculously, but if you were ever hopelessly addicted to a drug you'd understand the desperation). His "doctor" handed him a single page document that chronologically listed by the minute, hour, day, week, month, year the physiological effects that quitting smoking has on your body. From heart rate to blood pressure to circulation to sense of smell / taste to lung tissue regeneration it was pretty amazing.
Not dying from lung cancer is a pretty good motivator too.
Or you could just move to NYC with me, where cigarettes are $12 - $13 / pack. That's downright inspirational.
