It is better to follow instructions.
After being put under, no matter how lightly, some times we don’t know anything for several hours later, even if we act like we do and could make important mistakes that driving could cause a wreck.
My first time, guess they gave me too much of that stuff and they tell me I was awake right off and fine, we went to eat, then I picked up my mail at the post office and they drove me home.
That evening I looked at the table and there was the mail?
How did it get there?
I didn’t remember any of that, leaving the clinic, going to eat and getting my mail or what I did all afternoon.
Did I fed my horses properly and cleaned after them?
I checked and yes, they were fed and cleaned after, but I sure didn’t remember any of that at all.
No telling what would have happened if I was driving and had to make a quick decision when I was just not really there?
Next time I told them about that and they gave me less stuff and I was awake right afterwards and fine, no amnesia the rest of the day, like the first time.
One reason for someone there all the time is that some times, they have to do other that requires someone making decisions.
The third time, I had previous abdominal surgery for a mass that ended up not being cancer.
That surgery scrambled my innards so the gastroenterologist “could not get up in there”.
They woke me up, my friend had to drive me to the hospital where they finished the colonoscopy the old way, with a barium enema and contrast x-rays.
That is not as good, but second best to find anything there that should not be.
They have reasons for what they do, they have seen it all, so provide for any that may come up.
Better follow directions.
