A lot depends on you and how you respond post surgery & how long you stay in hospital.
I slept a lot & wasn’t interested in reading or watching anything I’d downloaded. Didn’t have an issue with dry mouth or lips but they were pumping me full of fluids. Best thing I did was bring my own shower gel, own pjs & general toiletries. Nothing felt as good as that first shower, smelling nice and putting on my pjs.
Wear home what you wore to the hospital.
Disposable knickers. The possibility of very sudden diarrhoea with no warning is a real possibility. Wish I knew to bring them. I got up to do a wee, took three or four steps and whoosh. There was no saving those knickers and needed a shower. Those medical grade laxatives are super strong too and increase the risk. A friend wore hers first a good week after: wet farts!
Make sure you have your over the counter meds (non NSAIDs pain meds, gas X, stool softener, Imodium, etc.) ready at home before your surgery. I got the scripts the surgeon gave me filled at the hospital before I was discharged. Make sure you have a script for nausea and a PPI as well as any opioids the surgery gives you.
A heat pad can be handy to help with the surgical gas shoulder pain.
Stock up your shakes, bone broths, cream soups as you’re allowed in the post surgery liquid stage ready surgery. Be warned, you may find what you enjoyed before surgery you dint like after as your taste buds temporarily change & I had a textural issue too. I found shakes too sweet and grainy & bone broths too salty so have a variety.
I slept in my bed in my usual twisted side position from night two. No need for a recliner or to sleep propped up. I was the same with my gall removal and hysterectomy so it’s a me thing and may not be something you can do. Didn’t have any issues getting in & out of bed or from chairs. Just go slowly.
Actually just go slowly is good advice for your whole recovery (it takes a good 6-8 weeks to be fully healed). And walk. Little and often is fine.
All the best for your surgery and hope you have an easy recovery.
