Hi CFS,
First off, have you determined that you are a compulsive overeater, or bulimic? Some people may find that they are just unhealthy eaters.

In a nutshell, The OA program originates from AA (Bill W's Big Book) where recovery is addressed through the 12 steps.

The guidelines to remain abstinent vary from one person to the next. For example, some people only eat three meals per day and weigh and measure all of their food, but that can be problematic for some. I am diabetic, so I have to eat more frequently, plus I obsessively count, so weighing and measuring can make me insane (which defeats the purpose). When I work with sponsees, I help them tailor A workable program that they can live with because there is no right or wrong way.

The purpose of a sponsor is to guide you through the 12 steps and work you through the tools of recovery. Some ask that you check in daily, but again, it should be reasonable based on your needs. Sponsors are supposed to be your go-to person for guidance reagarding the program (only), not tell you how to live your life.

If you can't get to a face to face meetings, there are phone meetings and podcasts, I'll post that info for you shortly. Any other questions, please ask away!

That happens to me sometimes and it's soooo frustrating

There are no short answers about OA. If you can't get to a face-to-face meeting, then get the literature and read it, listen to the OA podcasts, listen in on phone meetings. In order for the program to work, it requires first being able to fully concede to your innermost self that you are a compulsive overeater and that all your attempts to change your behaviour on your own have failed.
