Mine was an emergency so a little different, but I had the op on the Wednesday evening and went home Thursday lunchtime.
I first got out of bed 5 hours after the op, middle of the night for the toilet. Was horrendous but the first time really is the worst, every time you get out will be easier after that.
I had a drain in, so that had to be removed, and also had antibiotics as my gallbladder had been infected and starting to rupture, which delayed me going home.
The pain in my shoulder from the air was horrible, but only lasted a couple of days. The car journey home was the worst of my life, DH went very slowly but every bump made me shout out.
I refused anything but paracetamol and ibuprofen due to breastfeeding, but take what you're given and take painkillers regularly, don't wait for the pain as it can be unbearable before they work!
Lots of rest but try and get out for a small walk every day, the more you move the faster you heal and the fresh air really helped my mood, as I was so fed up of the pain.
I'd read about people going back to work a week or 2 after the op and can't see how they could. My op was in January and it was only really the middle of March that all the various pains stopped and I felt normal again.
And don't forget that even though the external scars are small, it's major surgery, you've had an organ removed. It takes time to get over that, so don't listen to people who expect you to be cleaning, working etc straight away. Just take it easy.
Good luck with the op :)
