I asked we surgeon once on the way into surgery, it was 10pm and I was delirious from waiting, nurse told me at 7 am that I was going to surgery soon! I requested a tummy tuck, butt lift and boob job. My surgeon laughed, and said if it wasn't so late he'd give it a go.
I didn't have any 'requested' optional extras done, but did wake to be told that they had to remove both my ovaries! Would have much preferred the tummy tuck and lipo.
