First of all, I am so sorry you're going through this

I stopped about 7 years ago successfully. I still battle the mindset, but I can happily say the habits of not only purging, but constricting diet and over exercising is over. And while I of course gained weight, I am a MUCH much happier person.

How did I quit the purging behavior? I quit cold-turkey. I woke up one day, and never did it again. Of course it was not easy, ESPECIALLY at first. The habit was so ingrained I felt sick to my stomach after eating anything. I literally cried as my stomach ingested the food and I knew some was going to fat. I wanted nothing more than to bolt to the bathroom and purge. There were moments when I would be standing in front of the toilet, staring at it, wanting nothing more than to resume purging. But somehow I walked away. And I tell you, there is nothing more empowering than walking away from that toilet. I never purged again. After a week, the urge lessened. After another, even better. And after a full month it felt like a distant nightmare. I started off constricting my food, and still obsessing over my weight. As I said, the mindset is a slow slow process. I did gain weight, but my husband found me even more attractive than before, and people seemed to like the new "me" better (probably because they could sense I was happier).

As another poster mentioned, there is no easy answer, because the biggest hurdle in this is YOU. But I am proof that you have within you the key to stop. But you have to want to. BAD. For me the motivation was my son, who was 4 at the time. I didn't want him to have a bulimic mother. He deserved the best I could give him. I also have a VERY bulimic sister who still, after 15 years, keeps going at it, despite the repercussions on her children. Her health and life is in turmoil. She obsesses about weight and food constantly, and is obviously messed up and unhappy. She states she wants to quit, but blames the world around her for not being able to. There was no way I was going to be like that.

Some people mention avoidance of purging, by getting busy or going elsewhere, and I am sure that helps a lot. But to me, that is still going forward with the mindset of "If I don't go and do XYZ, I could still purge". And the bulimics I've known may stop for a little while with this strategy, but eventually resume. I think the key is confronting the scenario of YOU being the only thing between you and purging. Not driving around. Not being busy. If you can confront the perfect scenario to purge, and STILL walk away, then you are strong enough to stop.

So if you WANT to quit, you will quit. All it literally takes is never doing it again. Not easy, I know, but very attainable.

Good luck to you, and big hugs
