Katie,
you are going to throw out your treatment group and your volunteering?
Some of my habits are more easily changed with a change of venue, for example, caffeine is a no-no to me, yet married with a husband who made coffee each morning and was not able or wiling to go decaf with me...I wound up drinking caffeine again.
We have divorced, no one is makiing coffee each morning and I don't miss it at all.
I am addicted to cigarettes. No matter where I go or whom I am with....nothing is going to affect the fact that I will always make sure I have cigarettes and feed my addiction to them. And I don't know what it will take for me even to think about stopping that addiction.
