Thanks Bettyann. I appreciate you taking time to respond. I do know that there was a lengthy preparation for this surgery and that the prospective patient had to meet definite criteria to even be considered. It’s now three years later and over the past year depression and addiction has taken over and the observation of a close friend noted that she saw a change taking place following surgery. Then a nurse who works with patients dealing with psychiatric issues has seen this surgery in their medical history. It has just triggered a big question in my mind and I’m anxious to get whatever feedback I can on this subject. Thanks again for your input.
