Thank you for this - I'm always concerned that people miss this. I recall someone I know noticing that they just didn't enjoy smoking anymore, and it was actually making them more anxious. Without going into a discussion about why this happened, it took them a long time to realize this because they were rationalizing their use, and using more to counter the fact that they were feeling "off" after the regular amount. As a non-smoker, it's one of my fears that if this happens again, I won't be able to convince one of my smoking friends that this is happening to them. Mental dependence seems insidious in that way. Any pointers? Experiences to share?
