Make sure that someone goes with you so that you have them there as you come out of the twilight sedation and that they can support you and then drive you home.
I've had several years ago.
The feeling of numbness on throat was troubling for me but only lasted seconds and before I knew it I had obviously fallen into twilight sleep and then it was all over and I was in a recovery area. I don't remember anything until leaving the clinic and the drive home.
all the best to you for your proceedure.
