Food Addiction Support Group
An individual suffering from a food addiction disorder frequently experiences episodes of uncontrolled eating, or binging, during which they may feel frenzied or out of control. They will eat much more quickly than is normal, and continue to eat even past the point of being uncomfortably full.

Sure, Christmas is a difficult time to start this. But if you look at it from another angle, Christmas is the absolute perfect time to jump in. Today's the 3rd; let's look towards the end of the month and include the New Year's celebrations, and you've got about 28 days of pure hell ahead of you. what's perfect about that, you ask? Well, in 28 days you can look in that same mirror and say you did it, you got through the absolute worst stretch imaginable as far as temptation and availability and stress and so on. You can shake your fist at the universe and cuss it out and declare your superwoman status. That's what I'd do anyway.
Sure, you could wait until January, but where's the challenge in that? In January everyone's feeling noble and spartan and talking nonstop about their rigorous diet and exercise and hideous New Year's resolutions. Starting it now shows a lot more imagination and independence and strength of character.
After all, who looks at themselves in the mirror on the first of February and congratulates themselves on getting through January without giving in to temptation? No one, I tell you, because everyone else was doing it too. There's no fun in that at all.
There are some things the rest of us have learned that will help you, if you want to get into that. But for right now, welcome, you're not alone, and you really can do this.
