I have been through this too--the fasting and binging. It is not easy but returning to the Master-Cleanse will only make it worse. We all have to confront our food issues not avoid them. Use this opportunity to look into causes and cures of bingen eating to begin fixing the real problem.
Being on the Master-Cleanse is wonderful because it gives us the perfect excuse to avoid our problems associated with food. But as you know aviodance doesn't work.
Please begin to heal what really needs healing.
