My focus would still be body maintenance, keeping the filters clean so we can keep the detox manageable. Its called cycling. Often it takes years to get everything under control. I learned this priority from my naturopath who I trust.
cleanse-rebuild-cleanse-rebuild...so after the Master Cleanse, its appropriate to rebuild, which means flushing the liver and rebuilding the volume in the blood before the next cleanse.
of course this would be my choice...and when a person presents themselves with a toxic body, you cant just clean everything at once...that can throw you into a healing crisis...
