I have tinnitus only when I think about it. The rest of the time my brain just ignores it.
I feel the same way - I forget I have it until I read about it, then i can hear it again (unless I've had too much salt or caffeine or something)
(I check sodium on the Nutrition Facts of packaged food (it's usually high), don't touch even decaf, don't touch alcohol, and try to minimize the bad kind of stress that has no constructive solutions.)
