I have read where alcohol and caffeine are two well known aggravators of
tinnitus.

Although I drink on occasion, I would not classify myself as a "big
drinker."  I'll often go many days without consuming any alcohol and, when I
do, it is usually in small quantities.

On the other hand, I love my coffee.  In fact, I think giving up coffee
would aggravate me more than having tinnitus.  I'm one of the fortunate ones
who, although having quite a loud and constant ringing, it doesn't really
effect my life that much.  I usually tune it out and am frequently
distracted from any awareness of having it.

Although, I can certainly sympathize with those less fortunate.  I think,
for me, I actually had tinnitus for many years before realizing it.  Once I
became aware of it ... my brain had already conditioned itself to tune it
out.  In other words, I adapted before I even knew I had it.  Funny story:
For a long time, I thought I had *better* hearing than most people, thinking
I was hearing subtle electrical sounds that many around me were missing.  I
thought I was hearing the hum of a fluorescent light, for instance.  Or that
I could hear the electric whining of some appliance, like a refrigerator.
And then, one day, sadly, I came to the realization that none of those
sounds existed.  But, by then, I had been conditioned to accept it.  I only
find it slightly aggravating when trying to sleep in a "dead quiet" room.

Believe it or not - I am an airline pilot and I have no difficulty with my
hearing.  The frequency of my tinnitus is not a functional frequency that I
typically encounter in everyday life.

I wondering if I stopped drinking caffeine products altogether whether the
condition would subside or end.  And then again, I don't really care that
much to even conduct that experiment.
