Hi! I have included a link here to the Reclaim Your Curves website - in particular their information sheets as there is one that hopefully will help you with the questions you posed - Preparation and Recovery as well as an info sheet on what to pack for hospital
https://www.reclaimyourcurves.org.au/information-sheets.htmlI too have had a mastectomy and for me it was more the tiredness from the anaesthetic and the emotional trauma than the actual surgery. Pain relief needed for me was minimal however I am mindful that we are all different
Here's hoping it is smooth sailing for you. Take care and best wishes
