Binging and Purging are no strangers to hypnotists who see these sorts of behaviors in people who tend to be perfectionists and have a poor body image. So I was pleased to hear about a study in the Archives of General Psychiatry on what these wonderful professionals call Bulimia Nervosa...
Brown, M.H. (1991). Innovations in the treatment of bulimia: Transpersonal psychology, relaxation, imagination, hypnosis, myth, and ritual. Journal of Humanistic Education and Development, 33(2), 50-60.
In this study it is cited that hypnotic techniques are very useful in helping with this problem.
