Overeaters Anonymous (OA) is an international organization dedicated to helping people work through their struggles with weight. It uses the 12-step program to address all areas of overeating, but does not endorse any one specific diet or weight-loss plan.
You don't have to register or be a member to attend an OA meeting. The OA website offers a search page that will help you find a face-to-face meeting in the Milwaukee area. Just type in your city or zip code, and it will list the days, times, and locations.
If face-to-face meetings are right for you, OA also offers online and telephone meetings.
