You can't underscore the value of lots of water daily, its good for the skin, gastrointestinal track, liver, kidneys etc. Before flushing, I had gallbladder attacks and the last thing you want to do is take anything that excites the liver, which in turn creates bile. After 2 flushes I began to take 25 drops of milk thistle to stimulate the liver, good stuff. Kidney cleanses contain Dandelion extract, and you can take it anytime, in fact its a good idea to go a kidney cleanse after flushes because of the load placed on the kidney.
