I have had surgery a couple of times, many times with general anesthesia. As much as I like to eat, I am not terribly bothered by fasting prior to a surgery. My main reason for preferring to begin the procedure on an empty stomach is rather basic;
I want to do my part, not to have any extreme ‘bathroom accidents’ during the procedure! Other than avoiding my profound embarrassment, I don’t want to waste the time of the Surgeons and their Team. Then, I would need to re-schedule that same procedure, with the problem still unresolved.
A second reason, going into most surgeries understandably makes me a little nervous. Like going to the Dentist, or maybe a Job Interview. No one really knows what the exact outcome will be, not even the surgeon knows 100%. When I’m that tense, it’s not easy digesting a full meal, plus any beverages.

Ditto. It’s the no drinking part that bothers me because ... coffee. The headache after surgery is excruciating.
