I am also having surgery on Tuesday... I haven't been sleeping well, my mind is racing! I keep thinking about all the bad things that could happen and I think im unconsciously trying to physic myself out. I actually had to stop going on the web before I go to bed so the information is not fresh in my mind. Of course we are on med restrictions so NO SLEEP MEDS! Your not alone im super nervious and excitied at the same time!
