I quit in the mid-1980's.
The only thing I craved was to immediately beat people senseless when they ticked me off.
I developed a lot of restraint during that period.

Hope your experience is more tranquil.
Yes, me too, exactly the same.
I quit New Year's Eve, 2003. I used Nicorette gum. I handled the cravings with the gum. It works. It's a little slow, it doesn't get to your brain as fast as the nicotine does from a cigarette. It takes about two minutes to go threw the chew-system and relax you, but I always found that it got there "just in the nicotine".
If you chew nicorette too fast, you can burn your throat. And it's hard not to chew it too fast when you're in the middle of a nic-fit, but try the "chomp-suck-savor" method instead of the "chomp-chomp-chomp-chomp oh, I need that" method. Kind of lodge the chiclet near the back of your teeth and chomp it every-now-and-then and just let those juices calm you down. Goes good with coffee, and after a long-enough cooling off period, it goes good with beer or Jim Beam. (Once you've got that mastered, you can try doing the coffee, beer, or Jim Beam in a public place where some smoker might just decide to light up in front of you. That's a real test. Leave, if you feel yourself crumbling. If you go long enough, you'll be able to take it when someone smokes in front of you.)
I weaned myself off the nicorette by switching to the Mexican Trident Bubblegum flavour of gum. It's called "Cool Bubble" down here, but any type of gun would have done, I just chose this one. I still chew Mexican Trident, always carry a pack. I wouldn't start smoking again if I couldn't get it, but in every way chewing a few sticks of Mexican Trident every day has completely replaced smoking.
If my Cruise Ship hits an old W.W.II mine sometime in the South Pacific and there's a life-boat with a Guess Jeans Girl in it that's full of cartons of cigarettes and another life-boat close-by with just a nice girl in it but full of packs of Trident Bubblegum, I'll take the nice girl and the gum. A few years ago, I wouldn't have. Immediately after quitting, it would have been hands-down for the Guess Jeans.
But you do get over it. It's just not something that's quick and totally without discomfort.
