Newly Diagnosed WA

Hi, I have just been diagnosed with invasive ductal carcinoma. I have decided to have a double mastectomy. I live in a regional town in WA so I will be flying to Perth for the surgery. Any advice for preparation for surgery. Will I need propping pillows to sleep post surgery. I am staying in Perth post op for 14 days to allow for the nurse care of drains. Has anyone else done this in Perth?
