Wordgirl,
There have been many discussions about neurostimulators. Thanks to Jo for helping you find previous threads. I think they will help.
I have a stim, and I don't know if I would do it again. One thing you will probably find in common from all stim users is - don't rush into it. Mine was implanted almost 14 years after the onset of symptoms. It is considered, by many, to be one of those "last resort" treatments. It is difficult to reverse if you don't like it or it does not work. Even with the most sucessful implant, has its own set of typical side effects. It is not sucessful in everyone. Approach carefully.
Good luck.
Mike
