From Dr. Amy Yasko, re. charcoal-magnesium flushes: "Dosage: 1 to 2 capsules of charcoal, followed by enough magnesium citrate to produce a bowel movement within 8–12 hours. Once per week or more depending on testing and behaviors." -- see
www.dramyyasko.com/resources/autism-pathways-to-recovery/chapter-6 for more info (search the page for "charcoal").
I'd highly recommend reading the whole section on CBS mutations, because that's where she explains how to deal with the ammonia, including instructions for the charcoal/magnesium flushes and how much yucca to use.
Dr. Yasko's protocol is not intended to treat Lyme. It is intended to compensate for genomic variants in the genes governing the function of the enzymes involved in methylation & closely related metabolic cycles.
My diet is strange right now (yogurt, pears, ginger candy, and IV nutrition). I'm trying to work my way out of a severe Gastroparesis flareup. Yes, I avoid sulfur as much as I can. I make up my own recipes.
