I don't know of any reason why you couldn't start right away. While Mr.Burroughs is dead set against enemas I have read of quite a few folsk including Somer that did a 59 Master-Cleanse
and the last 10 day or so juicing
that she did colinics every 10 days or so while on the Master-Cleanse
and had wonderful results. Browse the forum back till you find one of Somers post then click on all of somers msgs. She pretty much keep a journal here of her 59 day cleansing saga.
You'll probably have a pretty easy time with minimal detox symptoms on the Master-Cleanse
after cleaning out your bowels with colonics.
