It is difficult for sure and those urges may decrease in intensity and frequency but they don't completely go away. On my third try at quitting, I've managed to make it 3 years - it seems like an eternity. I'm very jealous of people who are still smoking but I love the smell and sit in the few smoking areas left. I only have a real urge about once a week and taking a very deep breathe seems to help get rid of it. I wasn't able to do that without coughing when I was smoking. It sure is nice not to have to go out in bad weather just to have a cigarette that really didn't taste that good before I quit anyway. After 50 years of having my life ruled by a nasty habit, it's great to be free from it and I hope I never go back.
