I can't write much as going out soon, but it sounds similar to me....and I'm sure many others too.
Oddly enough, once I got over all my emotional baggage behind this habit (two years of counselling) I became very good at maintaining my weight and eating a varied and excellent diet. Although from time to time high stress and dieting trigger it. Obviously, pregnancy was not an easy one to ride out with a history of weight problems.
I have just lost one stone (I have three more to loose). I tried earlier in the year but bulimia struck, so took the summer off to relax, think a lot about it, talk online about it and even mention it to my dp (he didn't take it at all seriously - I think he thought I was making excuses). Anyway, I decided to wait until there was less stress in my life (September seemed to be best). I eat 3eggs+toast+half grapefruit for breakfast, big healthy lunch, and then just eat a smaller supper with no carbs. Snacks are tonnes of fruit (which I love). It's worked quite well, twice I've binged but in seven weeks I think that is quite good for me.
I just really want to loose the weight for life and stay the same weight for the rest of my life, because I know I'm actually very good at that. The battle will be getting there. But it's going well, and I don't care if it takes a year - I just want to go very slowly and not become an emotional mess.
It's incredibly hard. I was my ideal weight 14 years ago for a few months, and before that was 20 years ago, so the vast majority of my life I've spent hating my weight, and I think I've reached the point where I am really bored with it, and just want to be free of it all. I think I'm almost there.
