I got divorced and that hi pitched noise went away....
No, seriously, I lost 30 lbs last year and brought my blood pressure down to normal after a few years of debauchery..The ringing is pretty much gone...If I cheat a little and have a few beers a couple of days in a row I can feel it coming back..helps me keep my health in check..
I should also add that I am a life long drummer/weekend warrior who still practices in a small room a few hours a week..Head phones help..
I'm guessing it was the blood pressure...
