I had mine done in 2013 and only had to stay in overnight.
I only took paracetamol the day after the operation and then didn't need anything after that. I didn't have to break them in half but i tend to take capsules so they are easy to swallow.
Some tablets i still can't swallow if they are too big.
I was advised to eat a sloppy diet for 6 weeks after so i had things like porridge
boiled eggs and soups then after that i was told to try mince but to make sure it had been minced through twice so i bought a thing called a mouli which was brilliant because it meant i could eat meat. I just did things like spaghetti
bolognaise and put it through the mouli ( not sure of spelling ) it breaks the mince down but still leaves it with a bit of texture so you don't feel like you are eating baby food.
Now i can eat most things but was told that i would never be able to eat steak
and i have tried but can't eat it.
I also can't eat much bread especially if it is really doughy but i am so much better than i was as i could not even get soup down back then.
One thing i was told by the surgeon is that there is no cure for this and the surgery is to alleveiate the symptons so there will always be things i can't eat.
It is just a case of learning as everyone i have spoke to seems to be different after surgery.
I read on one of these forum that some people eat burgers, steak, fizzy drinks and things like that but i can't.
The other thing is the acid reflux can be worse after surgery which means i can't eat anything spicy at all yet others eat chilli.
But i am so glad i had the operation and don't really feel like i am missing out on things.
The other thing is i need food that has a little moisture in it like mayonaise
and sauces or gravy with dinner unless it is something soft.
Good luck with the surgery.
