Would you be willing to share more details, instead of this rather vague claim? I've had three at least 2 hour long operations last year. I kind of wondered if I'd notice any aftereffects, but apparently didn't. Even waking up was pretty uneventful, consciousness just coming back like a light bulb being turned on again.
So either I am an exception, or your "everyone I know" needs qualification. In any case, I'd be very interested in what aftereffects you noticed, maybe that helps me reflect.
For me and others(in my circle with operations, 5) the waking up part is multiple hours of a drugged feeling, like you really aren't on the same planet anymore.
Currently have a family member in hospital and 4 days later they are still dealing with the effects.
I assume this is probably a regional/country issue, australian public hospitals are pretty sub-standard.
