I have not read any statistics on this, nor do i think they exist.  In
my case, it is on and off.  That is to say, sometimes it is there while
sometimes not.  But the most important thing is that even if i make a
deliberate effort to listen to it, it is either not there or there on
very low volume.  But then again, I have personally talked to two
persons whose T is completely cured.

You are better off quitting the AST group.  By going to this ng, you
are constantly reminded you have tinnitus, and it is unhealthy, unless
of course you need an answer from that group of people.

As long as there is sound but no somatic discomfort associated with
your T, i suggest you give your body or that part of your body that
causes T a chance to recover slowly.  You can assist your body to
recover by taking blood vessel dilating medicine.  The latter method is
what the Chinese medical establishment uses.  I personally recommend
med like gingko biloba, and devices such as going to Hot Springs, and
sleep with your neck resting in a wrapped towel, doing away with
napping during daytime, etc..  Remember, even if you do all the right
things, it would still take several months before you discover that T
slowly goes away.  There is no quick fix for T in most people's cases.

Good luck...T is not that horrible.
