Props man, it can be hard. I quit after 10 years of pack-a-day (30 ciggies) and it came down to a few important things.
1) Tied an elastic band round my wrist - when you want a smoke, pull the elastic band and let it go. It's instant distraction.
2) Got some Fishermans friends (little hot lozenges) - I'd eat one of them instead.
4) Heaps of support from friends and family.
5) Got myself pay TV - cost about 1/4 of what I was spending on smokes (In Australia it's between $10 and $15 a pack) and it reminds me how much cool stuff I can have with the money I saved.
Keep at it man and if possible, don't turn to donuts - I did and gained 15kg ( 33lbs) - I've only just lost that weight and it's been 5 years!
