I saw an integrative medicine doctor on Tuesday. He diagnosed me with CFS (no surprises there) and suggested I look up which of the cytochrome P450 liver enzymes metabolizes azithromycin (the antibiotic I took which caused my current crash), because apparently I'm deficient in it. His "solution" to fixing these issues is to do the detox diet by metagenics, dry skin brushing and dry saunas (all for detox). I suspect he recommends the same things to a lot of people, something I have found is common with a lot of alternative docs. I am also afraid the diet would make me feel worse, though, and since I am gradually improving, although slowly, part of me doesn't want to mess with it. Anyway, I just wondered if anyone had ever heard of cytochrome P450 enzymes before--it would go with the theory that ME/CFS is caused by a buildup of toxins. Has anyone tried one of the detox diets (metagenics, standard process, etc.) and if so what was your experience?
