The over-acid persons may suffer from symptoms of increased nervous irritability, dehydration and anoxia (symptoms of suffocation). Noise and excitement and other ordinary affairs of the day will cause them unusual distress. Dryness of the mouth and a “feeling of a lump in the throat” is common. Bright lights irritate their eyes and they prefer darkened rooms; bright sunlight often prevents their driving without dark glasses. They may feel “stuffy” in closed rooms, are uncomfortable in high altitudes, sigh frequently, and become breathless easily. They may be abnormally sensitive to pain. All of these symptoms are likely to give the sufferer more introverted personality traits, such as preferring to be alone rather than endure the friction of social contact.
