I quit 2 or 3 years ago, twenty+ a day. I went to sleep everytime I got a craving, went cold turkey on the Friday so that I had a weekend to get over the worst, told wife to keep herself and children away from me for those 3 days unless I came searching for them this was to ensure I was not angry with them due to my cravings. Get a hobby, everytime you get craving do that hobby you never know you could end up to a thousand miles a week on the bike if thats your hobby. I did the owning an tropical aquarium everytime i got a craving I would clean the tank, rearrange the plants etc etc best kept tank in Ireland !
COLD TURKEY to me it was the best as it is the shortest route to the nicotine being gone from your system and after that is is YOU that wants the cigarette not your body.
