Good luck on your test tomorrow. Hopefully, your doctor will give you enough sedation that you won't remember a thing.
I have had 5 colonoscopies and 2 endoscopies. The last one I had I remembered my doctor telling me to stop talking and relax. It's the only thing I remembered and the next day when I asked him about it, he told me I was asking him for more drugs. It was hilarious!!! I had no clue I said that.
