Surgery in 3 days!!

Hi everyone! I hope all is well. I am getting soooo nervous about my quickly approaching surgery date. Every thought of what could go wrong is racing through my head. I am having the laproscopic RNY and my surgeon is very well known for doing it laproscopically. I had to give consent for it to be converted to open if need be which everyone needs to sign. However, I am getting very nervous that it will have to be open, I guess out of guilt of the ten pounds that I have gained since begining the process. Does anyone know if there is a standard about open or laproscopic surgery? Anything anyone has done the last couple of days before surgery to stay sane?? Best wishes to everyone that is having surgery soon! Congratulations to everyone already on the loosing side! ~Kaitlyn~!
