When you say, "when you have that in your head there is no way to get it out" makes me think of it like an addiction, similar to overeating or even gambling or drinking. But there is a way to overcome it -- people do conquer their addictions! It's hard, I know, but I think you can get it out of your head. I quit smoking a few years ago, and it took about a year to really stop craving cigarettes. Maybe I should write an article about overcoming food/eating addictions, like laxative use, overeating, purging, etc? What do you think?
