Rev....sorry, I don't have any experience with this particular thing. (I don't even use a textin' machine (as stevetom says).
I have worked with alcoholics, though. To me, it sounds like a tool. Just like a hammer is a tool. It depends on how one uses any tool...I assume.
Just like Antabuse or suboxone is a tool......
I wish her the best.....
