Seamus, first 3 days is the hardest. Not everyone quits first shot.
I am on my 4th attempt and has been my longest run so far.
These are some of the things I did before I quit this last go around, they helped me a lot, might work for you too:
Stop smoking in your vehicle.
Smoke only one spot outside - Go only there to smoke.
Hold off on your first smoke in the morning as long as possible
Don't smoke after you eat a meal, wait as long as possible
Try not and smoke when drinking.
Don't finish cigarette, smoke 1/2.
Smoke only on even hours
Smoke different brand less tar
Break up any smoking routine
