Adding my good luck wishes for this Friday-
I didn't have any nausea from the anesthesia, but you can ask your dr to give you a rx for Phenergan just in case. I used it to help with the nausea I got from the strong antibiotics.
The one thing I do remember is that when I woke up I was FREEZING! They had about 5 blankets on top of me and then they brought several more. Also, I had a burning like I had to pee. The nurse said "We just removed your catheter. Trust me- you don't have to pee." I hollered that I most certainly DID have to pee, so she brought me a bedpan. Not one little drop, LOL.
Good luck- I hope it's as uneventful as possible, and wish you a quick recovery.
