I had single mastectomy and only stayed in overnight. I threw up most of that night as apparently gas and I don't mix so the next surgery was all intravenous with no gas. They do note when you get up and go to the bath room and if you have any difficulty or not. I just wore some knee high gathered around the waist night pants and when I changed out of the hospital gown i put on an open top with big buttons, easy to undo. I didn't shower that morning, just used wet wipes to clean the essential bits, brushed my teeth and put on a bit of body spray to smell nice. I ate all my breakfast and kept it all down so the doctor said I was good to go home about mid morning. Make sure you have some quality pain killers from the hospital to go home with. Just plain Panadol really didn't cut it for me after the first surgery so after the full axillary clearance surgery I went home with some Targin and that was very good. My breast care nurse had given me like a shoulder cloth bag some local ladies made. It tied around the neck and you put one arm thru and put the drain bag in the cloth bag so no one sees the icky stuff. Worked a treat. I also had a little pillow which tied around the neck and propped my arm away from my chest. It became my comfort pillow for weeks as it did stop me bumping my chest.
