I have also had 2 major surgeries while LCing. You might want to up the carbs a bit but don't go wild or you'll end up as I did: gaining weight back. I was once almost to 200 before the first operation and have had a hard time getting anywhere back toward that number since.

I also healed very quickly and felt well. Zinc supplements are good to promote healing and I took milk thistle to help my liver deal with all the drugs and anaesthetic. (I stopped it about a week before surgery and restarted it afterwards again.)

Stop the vitamin E about a week before. It has a slight anti-coagulant effect and you don't want that during surgery. It's fine to start again afterwards.
