Coffee slightly accelerates the circulation; taken too freely,
it impairs the nervous and digestive systems.
The nervous symptoms are usually
irritability, dejected spirits, weakness, trembling, watchfulness, mental
confusion, headache, dizziness, and ringing noises in the ears; the gastric
effects are flatulence, acidity, pyrosis, and bitter and sourish eructations, as
well as disorders of the bowels
