Every addiction takes will power in order to beat it. Try going to a support group for people that are in your exact situation. Talk, share stories and get advice from people who are exactly like you. I don't know if it would be Overeaters Anonymous, but you can always do a search online for local support groups in your area that can help you.
Also, when you get the urge to eat, just try and eat something healthy and snack on that. Easier said than done, I know. But, like I said, it all boils down to will power and how bad you want to beat your addiction.
Couldn't have put it better myself, it REALLY does take WillPower to beat this. I had the same problem, but the urge to break the cycle and not always be "the dude lookin for food" was extremely powerful. Because thats what I was, I was ALWAYS looking for food where ever I went, my friend's Parents started calling me "Cruton" because every time I went over I ate all their Crutons! Luckily they didn't care because they were cool, but at my house I was 10x worse! I wouldn't even THINK about it, my brain would just navigate my body to the fridge or the pantry, even if I wasn't hungry! And I'd just sit there and eat, eat, eat, and not even think "hey I'm eating this entire box of cheeze-itz", I'd get to the bottom of the box before I even realized how much I ate and be like, "damn, I can't believe I just did that".
Its been 3 weeks since I started my life-style change, and I get full quicker, I don't eat as much, and I've stopped thinking about food all the time! In fact...yesterday was a monumental day for me, because I went to eat with a friend, and I ended up leaving food on my plate because I got full, and I didn't even think twice about it! For many people that isn't a big deal at all, but to people like us its HUGE!
So Chef is seriously spot on when he says you REALLY need willpower to beat ANY addiction, the power seriously comes from within, to believe you can do it, because YOU CAN! It obviously helps to have the moral support of others, but again, it all boils down to the motivation, drive, and desire to beat these bad habits.
In the words of Thomas Edison, "If we did all the things we are capable of, we would literally astound ourselves."
You can do it, there is no doubt in my mind, take it step by step and day by day.
