@tniuf - brother - you've got it!
A bitter pill to swallow, of course, I know that, but tinnitus must have been around for as long as human habitation (40,000 years???) and in all that time nobody has been able to reduce the volume of tinnitus by as much as one decibel.
We mustn't waste the rest of our lives in fretting, weeping about the injustice of it all.
It took away my passion in life, the expression of my talent, my technique, my income, etc etc etc...
Involving the brain, the entire hearing system, it is obviously an incredibly complex problem - and may well prove impossible to fix.
I'm not being negative - the track record 'ain't great.' For goodness sake don't waste your life in regrets. It will make acceptance so much harder.
Perhaps organise some good hypnotherapy, or counselling, and start treating this as something you definitely will be able to take on board, and come to live with well.
I have just listened in to mine - and it's F¥€KING loud - but I haven't heard it all day.
Best wishes - and let me know how you are getting on.
