You need to be as holistic as possible in your cleansing efforts. Bowel cleansing is all-important, and the Liver Cleansing
should be comprehensive, not just flushing but herbs and such too. Vitamins should not be taken until after the liver is clean, otherwise it'll just clog things up more. vitamins are not great, I only recommend about 3 different vitamins, usually I recommend super-foods.
Try smaller doses of ACV, but don't stop it, it's quite powerful and will dissolve stones. Did you take it as part of the Cleansing Drink recipe? See the FAQ. Lecithin is also good. Peppermint tea, ginger tea, dandelion tea, Dr. Cabot's Livatone Plus or something similar, should all be part of your liver protocol.
I wouldn't recommend the coke flush because you are really mineral deprived at this point and the sugar/caffeine in the coke may compound this. check out my version in the FAQ on this page, it's similar to Julia Chang's flush, which is nice and easy.
