I read it quickly, as it is not very long. Here’s my impression.
I like the tone in that Geoff’s perpective is that we do not need to live with our tinnitus
It’s a clear, quick read
I knew a lot of the information already, however I was not aware of some of the herbal supplements he suggests
Contains good old-fashioned common sense
Worth it, but not a real “be-all end-all” solution
Basically, if you buy the book, don’t think that you’ll really have everything you need and you won’t need to “do” any more. The book will prompt you to take particular action, and it is important that you pursue actions that feel and are “right” for you.
