anesthesia
"I just had my second screening colonoscopy.  Due to a family history of colon cancer, my first screening was at age 40.  For that procedure, I was given Versed/Demerol, which did not work well for me.  It caused agitation, foggy thoughts, prolonged amnesia, and depression that lasted a couple of weeks.

This time, using propofol, it was a night-and-day difference.  I went out in just 5-10 seconds after injection, and I woke up quickly and smoothly.  I have full memory of the recovery room, speaking with the doctor afterward, etc.  I took it easy the rest of the day, but I felt fine, with no lingering amnesia or foggy-headedness.

For me, it will be propofol only from now on!"
