I am finding that my tinnitus doesn't really bother me much anymore. In fact, I'm not even aware of the "good" days as much. That is, I still have quiet days but I don't even notice those. I think that says a lot.
Oh yeah, the noise is still there, but I just don't give a damn. I find something else to think about. Time really does help.
I should add that next March will be 5 years.
