I felt I was reading about myself when I read your post. I am totally like you, I eat unhealthy stuff knowing its wrong and then regret it for hours later.
I too have grown this eating disorder since last few months and do binge on stuff secretly and then I pretend to eat healthy in front of other.
I am thinking of joining WW from this weekend, may be it will make me little more accountable. I need to get hold of my eating problem before its too late
