The biggest reason that most people have a negative experience with the liver/gallbladder flush is because they don't take the time to do the other required flushes/cleanses before doing the liver flush. It is very important to have clean bowels before attempting to do the liver flush. To have clean bowels means that you should have a bowel evacuation twenty minutes after you eat a meal. Another reason is that some people have a negative result is that they do not follow the requirement to eat a no fat breakfst and lunch. Some people don't have a clue how much fat is actually in some of the foods they think are low-fat.
