  == Purging disorder ==  I am experiencing the same problem.  I don't over-eat, or binge.  I eat only healthy, low fat, low calorie foods and limit my calories to 1200 a day.  I exercise everyday for at least three hours but every time I eat I purge.  It's gotten to the point now I don't have to make myself, the food just comes up.  I can't eat in public anymore.  I thought I had bulimia but knew my symptoms are differnt, I want to stop but I am terrified of putting on weight, so much so it is ruining my life.
