Nothing to do with your decision Shell but the last time I had a GA I couldn't hear a blooming thing after I came round When I woke the next day though my hearing was back to normal which was such a relief.
Nothing to fear in a Trans Cervical, MM, it has to be repaired anyway and better than incisions. The worst thing I remember about my last general apart from sickness was not being able to take anything alcoholic for a week or more, just tasted appalling.
