Hello Swedishfish and Beaglelover - thank you for your replies. I am not so worried about pain and nausea, I'm really sure that the hospital will take care of that for us. The fear of not using the op correctly as a tool is my problem. However as you say there is no more reason for me, or us to fail if we follow the plan. I will be thinking of you on the 29th, my surgery is in the afternoon.
Thank you both for repling so quickley. Only 3 family members know about this at present. They are really supportive but it is really good to talk to people in the know. Hope all is going well for you Beaglelover.
