I have found when working with clients who have addictions to implement something for them to hold/touch or for something for them to do with their hands. For smokers I usually implement a touchstone in which they have in all the places they usually smoke ie. one at work,their car,by the phone, computer etc. For alcoholics I have done the same. I have also taught many of clients with addictions EFT (Emotional Freedom Technique) some have suggested that they have not felt different in using EFT but it was a distraction for the moment when they really wanted to smoke/drink.
