Tom, good luck with your surgery. One reason you cannot eat or drink may be because of the type of surgery you are having in addition to the anesthesia. It has something to do with the intestines and needing them completely empty so nothing contaminates organs, etc. during surgery. When Jim had urostomy surgery he couldn't eat either and they made him drink that colon cleanse stuff. We watched a whole movie in the VA patient bathroom waiting for it to take. haha

Saying a prayer for a swift and smooth surgery and an early discharge.
