Hi,This is such a struggle. It affects self esteem and brings feelings of guilt. I understand what you mean by getting a fix. I feel it is driven by emotions and has nothing to do with legitimate physical hunger. It originates from emotions, anxiety, boredom, which is difficult to identify. I've heard of some group meeting which use the 12 steps, just like A/A. But this is a long process.
Hope you can find a way.
Take care
