Bulimia is not a physical problem that can be cured with fasting. It is a psychological problem that needs to be dealt with professional counseling. If you fast without having dealt with the issues of why you are bulimic you may wind up reinforcing the binge and purge that you are suffering from. I think you are looking for a simple answer to your problem but I'm afraid you won't find it with a 10 day MC. Get a handle on the issues and then try the fast...that is if you can get through at least 30 days without having the need to binge and purge.
