Oprah, on her talk show, speaks about psychological issues that make us fat in the first place - haunt us when we actually lose the weight. In fact, it is implied that gastric bypass can lead to alcoholism. Now that I am only a few pounds from my goal weight, I think more about why I was over-eating. One reason was the constant hunger - but there were other reasons too. I know this, because I would not over-eat when others were watching me.
I think the lack of the ability to over-eat tends to make us either address the real issues OR we find another vice.
Good luck figuring out what the REAL issue was.
