I am in the same boat. Goal 2 years ago, felt great. Got injured and in 6 months put it all back on plus 5 lbs. I love the "skinny me" analogy bc it is so true. A switch went off just over 2 weeks ago and I am back on plan. I figure 6 months back to my goal again and would love to go 200 days more without binging! I may have to take the odd day off to go out for dinner for celebrations and functions but I will keep that to a minimum.
I have a good life. A good job, a great husband and hobbies that keep me busy. I have NO idea why I binge. I have no weird issues in my past but I did have an obese grandmother so probably genetic?
