How to handle fasting before anesthesia?

I finally got my wisdom teeth extraction scheduled! (Yay!)
But the surgery is at 11 in the morning, and I have to fast for at least 6 hours. I could get up at 4:30 in the morning and eat breakfast. I don’t know if it’s worth it, though.
The one time I went till noon without breakfast, I fainted. Just from the lack of food. I don’t want that to happen this time!
I’ll definitely take it easy before, when I’m low on energy, to avoid fainting.
But is there a way to psych myself out and forget about the hunger? Is it just a matter of occupying myself with other things?
Do you have any suggestions for anything filling to eat before?
Any other suggestions?
