Thanks for starting this post Ron.
All I can add is that my quality of life was appalling when I had DBS 4 1/2 yrs ago.
I was desperate and quite willing to try anything and did.
It's not something we'd do without much thought but it was for me and many other PWP I know or know of the most miraculous of life changing events we'll probably ever experience health wise.
I'm starting to sound all American now so I'd better leave it at that!
