I am not a sponsor but I saw that no one had responded to your post. I have just recently returned to following OA. My sister and I went many years ago (20?) and it really worked for me. The buddy system was a great thing too. Many pounds later, I am back at it and trying to abstain from overeating. It has been 12 days and I am already feeling but better.
So if you are looking for a buddy to talk about the steps and to be of support, we might be able to help each other.
One for every twenty pounds lost!
