LadyRose- I'm going to suggest to you that it's not mental at all, it's the addiction that causes you to look for distractions.
Non smokers don't need to find distraction, because they are not battling nicotine withdrawal. Understand that your withdrawal is what is making you pace and crave something to do! And congratulate yourself, because you are getting clean. I promise (as someone who quit after 20 years, ten years ago) that once the nicotine has truly left your system (and it can take weeks), you will enjoy not having
to get up from the dinner table to go smoke, because nonsmokers don't need to leave- they can stay at the table and still have a great time enjoying the company of those around.
And I can tell you, that for me, playing with puffs every now and then, did me no good whatsoever. I tried innumerable times to cut down, only smoke when I was out, limit myself to three whole cigs a day - you name it. But being addicted to 3 cigarettes is just the same as being addicted to 20 or 40. It's additiction, plain and simple. I personally had to get mad enough about having no real choice in the matter to be able to quit for good. Alan Carr's "Easy Way to Quit Smoking" was worth it's weight in gold! It helped me realize the full and awful extent of my addiction, and made me realize what it would take to quit - and that, simply stated, is to never smoke another cigarette again!
