How can i stop doing this food addiction?

Food Recovery: You might want to consider attending a meeting of overeaters anonymous. Meetings may be found using their web site: http://www.Oa.Org/.

Seek help/food diary: It is well worth it to find a provider specializing in addiction and food to help you explore your eating issues. While you're searching for a provider, keep a food diary -- what happened before you started eating, how did you feel before and after you ate on the emotional level. The diary might help you to see patterns in your eating, which will be helpful in resolution of the problem.
