I would recommend working with an ED therapist to help you to understand WHY you binge eat, and to reduce/eliminate the behaviors. (To find a therapist who specializes in eating issues, click here:)
In the meantime, I would highly recommend that you pick up a copy of, and read the book: Overcoming Overeating by Jane Hirschmann and Carol Munter. Many people who struggle as you do have gotten a lot of support and relief from this book. http://www.amazon.com/Overcoming-Overea ... 076&sr=1-1
The key to healing is to work with a supportive therapist who can help you to understand WHY you eat when not physically hungry. Good luck! You can do this, and should not have to suffer anymore.
