I've just come out of my surgery on October 8th. All went very well - apart from just after the op, I've only had a bit of discomfort during the night.
Couple of recommendations for hospital -
1. face spray - I got quite flushed and found a bit of moisture really refreshed. I had a green tea spray which also smelled lovely.
2. chap stick
3 bottled Water - the hospital only gave me tap water which smelled like chlorine (might have been extra sensitive to smells after the op)
4. if you're a coffee junkie, arrange for someone to bring you in a decent cup in the morning. It makes you feel so much better having a coffee, if that's what you're used to.
5. Dry mouth spray - I didn't get this but I was wishing I had because I went more than 30 hours without drinking (had the IV fluids but my mouth was horrid)
6. Mouthwash - again, your mouth feels like horrid so it's good to refresh every time you go to the bathroom
7. Soft toilet wipes - just in case you get diarrhoea
8. Your own pillow - anything to make you more comfy
9. Soft t-shirt nighties - you really just want something soft and comfy to wear in bed.
