You can drink the apple juice any time. It will do its job no matter what or when you flush.
coffee enemas are best done when you're drinking a LOT of juice and not planning to Liver Flush for a week or so. They are very strong adn do cleanse the liver, best to only do them once a week or two weeks at the most.
By deep enema I mean taking in more water than a Fleet or bag. ;) You can do a simple water/salt enema too, they stlil clean you out! ;)
Dandelion and milk thistle are fantastic for detoxing the liver. Go ahead and take those until you run out. STop taking them for the three days surrounding the flush so as to not overwork the liver.
