Hi i have done 2 bowel flush, 1 parasite cleanse, the kidney and now the liver / gall. All in that order. i had no problems with any other. I am doing this as a general attempt to cleanse after years of meds for various illness. The food intake at the start of the cleanse was as intsructed, just organic friuts and veggies. I felt a little ill on day one after drinking the garlic, got worse on day two morning, then in evening started with headache and small vomit, not to much pain ,just nausea. Thanks, A
