I went cold turkey about 18 years ago and haven't had a smoke since.
I found quitting to be a strangely personal and private affair,hard to explain what I mean but in a way,perhaps a bit like an individual type sport where all effort and reward belongs to you alone.
I came home from work one Thursday night and vowed (to myself) not to smoke again. I told no one because I expected that others would feel kind of threatened by someone having a go at doing something they couldn't do and pressure me into failing.Was a bit concerned as Friday nights I always went to the boozer and I worried how I would cope with a few under the belt.Took a packet with me and challenged myself to get thru the night without having one but with the knowledge I had them if I needed to. Got thru ok and was so pleased with myself I chucked all my smokes and paraphernalia away the next morning. Although I still wanted a smoke at times,I felt I was in control and was surprised at how easily I found it after that.
Good luck to those who may have a go,the first few days are the worst but if you can get thru them you will be surprised at how quickly the edge goes off the craving.
I think you need to WANT to give up rather than try giving up because you think you SHOULD,be it for health or financial or whatever other reason.Attitude is all!!
Sorry for preaching
