Well, like with other eating problems, the most important thing I can say about recovering from Bulimia Nervosa, the number one tip for recovering from Bulimina Nervosa, is to try to get help from somebody experienced with dealing with these types of eating problems.
Sometimes that means an individual counselor, a therapist, sometimes that means getting help from a more structured treatment center, that can provide even around the clock supervision for breaking the cycle of binge eating, and purging.
That would be the number one tip, and sticking with the recovery process, and not giving up, even though there are bumps in the road, would be recovery tip number two. There are also some self-help guides that folks with Bulimia Nervosa can use, that are rooted in good science. Routed, for example, in good, sound, cognitive behavioral principles, that can be incredibly helpful to people. Actually, self-help has been tested in some scientific studies, as an alternative to more formalized treatments, ultimately with formalized treatments, behavioral therapy, with a therapist really being superior, but self-help can be helpful in some cases.
There is one expert in the field of eating disorders, Christopher Fairburn, who has written a book called, Overcoming Binge Eating, which is one example of a self-help guide, that's really routed in good science of psychotherapy that can help people get better from Bulimia Nervosa, and present some of the same principals that you would receive in a treatment.
Of course, nothing takes the place of working with a professional, in a treatment setting, to move forward in the process of recovery.
