mameulah whilst there is an element of biological urge to binge, typically driven by attempting to restrict and control food intake , and/or having what I believe is a particular sensitivity to 'trigger' foods (typically sugar and or starchy carbs), there is almost always an emotional element to bingeing.
Attempting to fight the urge to binge will never cure it. Bingeing serves a purpose for the person doing it - it is a coping mechanism or comfort (however bad it leaves them feeling). They may be suffering from repressed emotions, a lack of love and intimacy, work stress, problems in relationships (past or present), low self esteem, hatred of body...almost anything.
The poster above who found that religion solved her problem overnight is a great example, as is the one for whom having children was the change. They found a new and nourishing focus for their lives. It can be emotional or spiritual but it is an adjustment in these areas that will stop the bingeing. You must look at what your triggers are and where there are sources of stress or unhappiness, or something missing in your life. It will be different for everyone but address those things and the compulsion to binge will lessen, if not disappear. Not easy I know, but necessary..
