It can take anywhere from a day to several weeks to start passing mucoid plaque when doing the p&b cleanse...everyone responds differently. It's fine to use juice...but best to dilute it...fruit juice has LOTS of Sugar in it...often more than soda!
Stop the shakes the day before a Liver Flush and don't start them again until 1-2 days after. coffee enemas are great...powerful liver detoxifier...just make sure that your bowels are moving well if you're going to do them so that the toxins will be rapidly expelled. If you're backed up the toxins will get reabsorbed into your body and make you feel pretty crummy.
