I echo Steve the ORC on the warning about cigars. I quit cigarettes- several times- usually when I had a severe cold- but started again. Then I quit for a month, but the craving was there. I started on cigars, since I figured that I would just puff- not inhale. The old story! Cost me more. Cigars were expensive- why smoke weeds when good Cuban cigars are available here in Canada?
An operation with a few days stay in the hospital, and I quit again. This was about 1985 and it took. Haven't smoked since.
When I travel I get a non-smoking room. Once they sold out my room and I had to stay in one on the smoking floor. I couldn't stand the odor and dozed much of the night in the lobby.
Luckily all public buildings and stores and most restaurants here are non-smoking, so no cigarette odors.

Keep it up!
