Namaste all,
Thank you for your comments, suggestions and kind sympathy. I had never heard of Ginko Biloba's effect on tinnitus before. Will certainly try that also!
So this latest outbreak might be self-inflicted. Sort of serves me right, eh? Being stubborn (yes!) and a bit impatient I want the job done now, preferably yesterday, once I've made up my mind. And we are "happy amateurs" in this area so if it can go wrong it will. These kinds of projects teaches you a lot of your willingness to compromise... A tough lesson :))
I think I got the answers I needed.
Love and Light
Brit
