Easy food, button up shirts, easy to remove pants/shorts, rearrange your most used space/items so everything can be easily reach at about chest-face level, dry/leave on/wipable hygiene products for the period of time you can't shower, enough pillows to prop yourself/your arms up, benadryl for when the bandages start itching, so much entertainment, and my all time bestfriend was the grabber claw.
I was given drainage tubes and a pain ball, which was a local anesthetic in a pressurized ball with two small tubes connected to the center of my chest, because of this a realized much much to late that during my homecoming someone should have put up my jumpy dog until i was safely seated with tubes out of reach. If you get tubes and have a pet that risks pulling them do not be like me, it was very painful and I almost had to go back to the hospital to get it put back. Also if you have drainage tubes prepare yourself for it to be gross and painful and annoying, it does an important job but because of the location they can be easy to bump and mine didn't get the local anesthesia because they were to far from the injection site. They were definitely the worst and most painful part and on top of that having them removed feels very unsettling.
There is also sometimes some leakage, this scared me into thinking my nipple was infected and between my panic and an urgent care doctor's neglect it was drained and that ruined the results a bit. Make sure to look for other signs of infection like swelling and redness not just the leakage before panicking. Follow your surgeons advice as closely as possible, a lot of the reasons surgeries end up botched/wrong come from bad post OP care so be careful.
And the last warning I can think of right now is a little tmi, wiping after using the bathroom is going to be the one of the hardest tasks you can do. I never really found a solution but I wish I had been warned and had a chance to try and practice first.
I had to learn all of these things the hard way during or after my recovery, despite that and it getting way more complicated than it typically is top surgery was genuinely the best decision I ever made and im still very pleased with the results.
