Never even looked into the coke flush so I don't know... the diarrhea which is caused by the Epsom Salts gets me feeling crappy so I need my electrolyte supplement and I feel just fine. All my flushes have been productive ones, no nausea and I've always gotten stones.. Hulda Clark method worked miracles for me already.. Just got to make sure you take care of your body after the flush or it will suck recovering for a day or two.
