Tinnitus - do you have ringing in the ears?

I have had tinnitus for about the last 6 years. It just started one morning (at least that is when I noticed it) and has never gone away. It is worst in the morning, but most of the time I don't even notice it. I have tried MDs, DCs, herbal treatments, diet changes, exercise, no caffeine and other remedies without any success. Fortunately, when I listen to music, I don't hear it. If anybody comes up with anything that has actually worked for them, I would love to hear about it as I am willing to try just about anything.
