An article on a local newspaper reports a story in which a woman in
Indonesia has managed to have her age-old migraine cured by eating used
coffee remanent.  Now she eats the used coffee remanent everyday as
part of her meal.  Fortunately she works in a restaurant, and there is
no shortage of used coffee remanent.  How the mechanism works is beyond
me, as I am no doctor, and I am not sure if this phenomenon can be
proved using 'controlled' studies and as such be applied to every
migraine patient in the world. But i do recall once a doctor told me
that caffeine is blood vessel dilating.  By dilating blood vessels,
caffeine makes better blood circulation in the head.  As a result of
better circulation, pain is either lessoned or goes away.  The
explanation of pain by the TCM doctors is that pain, or its sensation,
comes when blood circulation is blocked.  Thus i venture to suggest
that tinnitus, or its sound, can come about as a result of poor blood
circulation.

I personally have found a connection between drinking coffee and lower
tinnitus sound.  And I would like others to contribute their
observations.

A word about coffee: I always drink brewed coffee and try to stay away
from instant coffee.  The differences I have experienced are:
(1)Instant coffee keeps a person awake for many hours while the effect
of brewed coffee goes away quickly.
(2)Instand coffee produces constipation while brewed coffee does not.
