From what I remember, full body anasthetic administered by an oral gas wasn't all that bad.
I remember my mum holding my hand as the doctor counted backward from 10... I made it to 7, maybe?
The next thing I remember I was in a recovery room, ready to run around the room.
But before long there was a nurse by my side, followed shortly thereafter by my mom, It was nice seeing a face I recognized. Not entirely feeling like myself yet, but feeling more at home.
It was nice...
I don't remember much past or before the surgery, which was, from what I recall a inner ear infection, and a treatment to release pressure from within the inner ear canal.
All in all, you'll be back at the computer that very same night, telling us about your experience, which you should.
Best of luck ^-^
