How to release addictive behavior?

I've been pretty sucessessful healing my ego based behavior but I'm finding that I'm having a hard time letting go of my physical addictions, like caffene, chocolate and cigerettes. I'm being strongly urged to let these things go, but for some reason I'm having trouble trusting my inner guidence. I've been meditating on releasing my resistance to change and it's helping some. Does anybody have any words of wisdom?

Thank you kindly.

Much love,

Suzanne
