I was a 40 a day for 20 years man and gave up, cold turkey 17 years ago, for love. I'm still with her and this is how I did it.
1) I booked a 2 week holiday a few weeks ahead (not to go anywhere but just so I would be able to concentrate and not have any distractions)
2) Up until the holiday, I smoked my head off, smiling as I went, knowing that I would soon be rid of this awful habit that I sadly loved so much
3) During the lead up to the holiday, I was psyching myself up in various ways and in so doing became very bossy and overbearing with everyone I came in contact with, as I was preparing for the biggest fight of my life...GIVING UP SMOKING!!
4) By the eve of 'D-Day' I was so hyped up, I actually flushed away 30 cigarettes I could have smoked that day. I couldn't wait for the fight to begin
5) Guess what? It was a doddle for the first day, even the second day was okay. Expect to get irritable and drink plenty of orange juice.
6) DANGER: You think you have beaten it and that it was so easy, you could start smoking 'socially'. WRONG!!! Light up again and you will be smoking even more, as I proved to myself in previous lame attempts to kick the habit
6) One of the reasons I was reluctant to give up smoking in the past was because I liked a drink in a pub and drinking and smoking go hand in hand. So instead of stopping smoking AND drinking, I went to the local pub, put a sign on the notice board saying that I would give £100 to any charity if anyone saw me smoking at anytime for a period of 1 year. I then carried on enjoying my drink BUT whereas the pint would remain on the bar during my smoking in the past, I now found myself holding the glass all the time (you need something for your hands to do when you give up smoking) and as a result I was drinking more and quicker. I also ate more during the day but I never smoked another cigarette again and I didn't wear any nicotine patches or chew gum.
RESULT: I gave up smoking and within 2 weeks my appalling morning cough had gone but over the first few years I put on 4 and one half stones. Half of that has since come off.
Bye the way: During the weeks I stopped, I went and bought myself a new suit with the money I saved.
