ECHOES,
Have you thought of using hypnosis to help with this issue? I have had the opportunity to work with a few clients for Tinnitus, and have had very good results.
If you would like to research this more, one of the first websites you will find will be Kevin Hogan's site. He is a Psychologist/ Certified Hypnotherapist who is known in the hypnosis community as the go to guy when you have questions regarding this issue. I will post a link to his site below. I also noticed on his site that he sells a CD program for Tinnitus. I don't know anyone who has used this, but based on his reputation I would bet it is good.
