Email them. They are usually quite prompt and courteous in reply. Be aware though, because of all the mud and persecution the establishment has drug Clark through over the years, her web site staff sort of has to tiptoe on eggshells in answering medical-related qutestions, only because Big Brother is just waiting behind the scense to have another chance to lower his heavy hand on her for divulging medical advice...... yeah, I know, such a wonderful system we unkowingly contribute to in this land, in all it's fully bloomed corruptness. I would still email her info site. Be sure to provide them any significant details, such as, did you strictly follow her regimen?; did you omit certain steps, like, the colon flush, or parasite flush, or the bladder flush, etc?
One thing I've gotten from her book is her comment from case studies where people did the final phase of the L/G flush without having done the parasite flush, and this caused these people to feel ill for several days.
