I have found that I smoke less unless we are in a smoking environment (ex: bar)

That's exactly why people with addictions must change their lifestyles, if only for a time, in order to learn to develop coping mechanisms to use when faced with temptation. For example, alcoholics are counseled to avoid bars and situations where alcohol will be used in the early stages of recovery.

I avoided many of my tobacco using friends and situations where smoking would be occuring for several months until I felt confident enough to know that I could resist the urges to bum a smoke.

BTW, if you are trying to quit, it's best to avoid alcohol if you associate smoking with it. Alcohol also reduces your willpower and has tripped up many a quitter.
