I have suffered from Tinnitis
for about 34 yrs. (too many
shotgun shells fired in my
youth at a 'range' that was
poorly designed with concrete
bunkers behind the firing area.)

I have not found anything to deal
with it except more noise. I sleep
with either a TV or a radio on everynight
and listen to one or the other all day.

But the high pitched hiss prevails,
apparently til death do us part.
