Gee, all your stuff resonates so strongly with me.

I recently began doing coffee enemas with instructions from Premier
Research Labs in Round Rock, Texas, which is run by a
biochemist/nutritionist, Dr. Bob Marshall (www.prlabs.com), whose
research and products are very high end and pristine, with the
products priced reasonably. What I would add to what you have
provided are the following:
~ Premier’s quantity is one quart with two tablespoons of beans,
done in two rounds (which may be more comfortable for some people).
~ The coffee beans are to be freshly ground before each enema to
preserve the phytonutrients.
~ During the first few enemas, there may be nausea during or after
due to toxin release.
~ Premier also recommends some additions to the water of their
products (capsules broken open) for immune support or female
hormone balancing, as well as drinking a cup of half aloe, half
water after the enema.

The Web site is worth a visit, and the toll-free number has trained
staff at the other end who can pass on a practitioner list as well.

~ Premier sells (cheap) a biocompatible-plastic enema bucket, so we
can all avoid the rubber or whatever.
~ Their #D-54 Premier Coffee Enema Procedure sheet is one of the
most clearly and comprehensively written set of instructions I’ve
ever experienced.
