"...avoiding others who are smoking" because of the temptation to smoke? More likely you keep your distance because of the way the smoker smells. When I quit, my sense of smell became very acute- some smells made me gag, literally. Dirty ashtrays and people without a recent bath were the worst.

One other trick I used when I was quitting, I stood a lot. As soon as I sat down, I wanted a cigarette; as long as I was on my feet I could handle it. I walked a lot too.

Good luck, both of you. You can do it, and it won't be long before you are SO glad you did.
