My DH did quit cold turkey (so did I, but I was pregnant, so it's a different story). DH read an article many years ago that you need to plan to quit. Pick a date (in the future, but not too far off) and then plan on it. Work up to it. Say to yourself that on XXXX date you will quit and STICK WITH IT. It did work for him.
I do have to say that it's been over 16 years for me and about 15 years for him since we "quit." I put that in quotations because it did not happen overnight. After DD was born, I still had urges--especially when having a cocktail or when going out with friends. Sure, I bummed a smoke from time to time, but I didn't let it make me go out and buy a pack and start up again.
DH and I have been on a couple of cruises where we actually bought a carton to take with us for the 10-14 day cruise (we went on two). We smoked like we didn't care. DH even bought cigars and we smoked them (yes, we). But when we got home, we threw away all the leftovers and went cold turkey again. It's been about 8 years since we've been on our last cruise, and probably about 3 years since I've smoked (DH has probably had a cigar here and there since then). But after all the years we've not smoked REGULARLY, we no longer have the cravings.
Every March we have a HUGE birthday party (there are about 15 of us born in March or April) and we always have it at a bar that allows smoking (outdoors) and this was the 2nd year in a row that I did not feel the urge to smoke. This is a long time coming. You really need to plan for it. You can't expect to say tonight that tomorrow you'll quit. IMO, pick a date in January and work up to it. Cut out a cigarette or two every day until then.
Best of luck to you!!!!
