I copy paste for you from Dr. Lawrence Wilson site:
"For most people, one to four coffee enemas daily are excellent. If one does four daily, I suggest doing two enemas back-to-back in the morning, and two back-to-back again in the afternoon. This has the most powerful effect, yet is very safe.
However, begin with no more than 4 tablespoons of coffee daily. More than this can cause nervousness in some people. Others can handle up to a total of 6 or 8 tablespoons of coffee daily."
Are you exceeding these 6 or 8 tablespoons recommendation?
Another question is what is your diet? Are you eating enough cooked vegetables?
Again, copy paste from the Dr. Lawrence Wilson:
Cooked vegetables are "extremely high in trace minerals. This is probably the most important reason for this diet. Most people are mineral-starved today! It is one of the most common problems on our planet. It is due to our agricultural methods, eating refined foods, stress and other factors.
Vegetables must be cooked well to obtain all the minerals that are locked inside the tough vegetable fibers. This is why the diet does not include raw salads."
