Like Marian & Traveller, I still have fleeting moments of craving, even after 7 months of quitting! That's why, I keep NRT lozenges with me (although I haven't used them for 3, 4 months), and still need one or two puffs from the NRT inhaler when the craving becomes unbearable!
The road to complete freedom from nicotine is long and hard, especially for me - a smoker of 35 years. However, I'm confident that this will be my last quit and I will succeed! :-)
