The purpose of digestion is to take the food that is eaten and break it down into nutrients-basic materials that the body can use. If one has indigestion, one should completely avoid all food, juices, coffee, tea, cocoa, herbs, vitamins, supplements, alcohol, tobacco, marijuana and narcotics, except the drinking of as much water as to satisfy one's thirst. Diet is not everything. With indigestion, avoid the emotional stress of worry, anxiety, fear and depression. Completely avoid the current orthodox digestive problem medical treatment of drugs and surgery.
Indigestion requires physiologically resting the digestive tract, i.e., water fasting.
One ideally water fasts, by abstaining from all activities, lying down, closing one's eyes and feelingly meditating on one's symptoms until one is asymptomatic. When one breaks one's water fast, i.e., when one eventually becomes asymptomatic, and one begins to eat, eat correctly. Never do anything that does not improve one. Do not do things from which one must recover. Eat only when one is genuinely hungry, not just because Dr. Ivan Pavlov has rung the bell.
