I’ve only had 2 bad experiences with anesthesia itself- one where I was really struggling to breathe when recovering- lasted about 20 minutes- and another time where I was freaked out for 32 hours straight- all the other times I was fine. I never worry about it before going in, as I don’t really care if i wake up or not, but it is how I awaken that gets me. Dying under anesthesia seems to me, personally, to be an easy way to go.
That's what's called "hospital psychosis". Has happened to my husband twice and the last time he was literally crazy and uncontrollable for 30 hours in the hospital. We took him home against doctor's advice and it lasted for another 18 hours at home. He finally crashed and slept for 24 hours straight and woke up in his right mind, thank God.
Now we know not to let him be admitted unless it's life or death.
