Good luck Sophie,your surgery day before mine,my last section I had to go in day before for prep,I think because you are being possibly operated at the jujenum,you stomach contents have to be completely empty so they are possibly making sure prepping is spot on that's all,I have to be there at 8.00am Thursday along with his other patients for that day,I hope I am first to be honest so I don't have to sit about getting over anxious.Good luck Sophie,hope all goes well, let me know how you get on, xx Trish
