I hate doing the enemas (but then, I just hate putting anything up my butt) but they are quite helpful in (a) preparing for the Master-Cleanse and (b) if for some reason either the SWF (Salt-Water-Flush) or lax tea hasn't worked. There is no way an enema will not yield a result.
I have the book and it think it said NOT to do an enema at any time but Burroughs is dead soI can't question that and Somer is alive and well, see a nauropath (sp) reguarly and completed 60 days using them with no ill affects so I'm going with Somer!
