I did my 5th flush last week and I know I re-absorbed toxins. I feel run down and tired 6 days later and I have a strange one-sided headache. :( I read here yesterday that someone (sorry I don't remember who, Flowerchild maybe?) said they use P & B shakes instead of an enema. When do you drink the shake? After all of the morning doses are done? I am doing the modified Clark recipe with a second dose of oil in the morning because that seems to work better for me. I tried to buy an enema kit and tried three drug stores and could only find the Fleet disposables. For now, I want to try these shakes.
