Mare:
I have read that nicotine is among the most addictive substances. You have made it 2 years now. That is pretty good. I quit smoking almost 21 years ago. I don't remember when the craving went away, but I probably had it at least 2 years. Eventually, the craving went away. I cant stand to be around the smoke now. However, I occasionally still have dreams that I started smoking again, and wake up to discover it was only a dream. In my dream, I was dissapointed. Good luck in your continued non smoking lifestyle.
