I never post in this section but I heard parts of this program on the radio yesterday and it sounded amazing so I had to post. The guy featured in the show (Dr. David Kessler) was the head of UCSF and Yale medical school and has battled food addiction. From the parts I heard he had a lot of interesting things to say. He has done studies with food addiction and cigarettes and recently wrote a book. If this is your struggle I would highly suggest listening to the program. Unfortunately the audio is not up yet but I am posting the link anyways; I would think they should have the audio up soon so that you can stream it over your computer:

Even as a person battling alcoholism I think he had some great insights into addiction. But having a primary focus on food it made it very interesting.
