Three years back I quit after 10 years of smoking (cold turkey). My notion of smoking was associated with break from work. So I replaced it with green tea and red tea(rooibos). You can probably give that a try. Another thing that helped was sports, I started playing squash. I tried to be in better cardiovascular health to play squash, another motivation. Maybe you can pickup something (gym, any sport or anything physical)if you are not already doing that.
