Hi there,
I had this operation in March. I had to be there for 8am (nil by mouth from 11pm the night before) bur then found I was no 2 on the afternoon list so I did get a bit hangry before the op. I was still home by 8.30pm.
Tips would be to take nice slippers and a fresh clean dressing gown. You’ll feel nicer for that and I had to walk through the hospital to go for the sentinel node trace injection so was glad to have something decent. Also take stuff to read/puzzles/headphones. They gave me one of those heart cushions at the hospital but I had one anyway. I found it helpful.
Hope it goes well xx
