I'd had GA many times for previous surgeries, never had the nerve block thing. I talked to some people about it including some nurses and made the decision to go with the spinal nerve block and sedation. I can say that it was a good deal for me. It is kind of strange losing all movement and feeling when it takes hold but then they put you into sedation and all is good. When I awoke in recovery, I was wide awake and not drowsy or sleepy at all. No lingering side effects from GA that I remember from previous times.
