Hello,
I had my surgery just over a year ago. You will feel very light headed after surgery. I had very little pain in my stomach, but had quite a bit in my shoulder. I know it sounds strange, but it's to do with the gas they use to help the procedure. I'm telling you this in case you get it and find it unnerving! It does go though, and most people don't get it! The other thing is to follow exactly what you are told about weaning yourself on to different foods, it is baby steps and baby bites. I still, even a year on, have to remind my self to chew to a paste, or things will get stuck.
By the way when things do get stuck, (and this is inevitable) really try not to get too anxious, it will feel like very bad indigestion, but the food WILL pass down, or up, and you will feel better then, and add it to your list of things/foods to watch out for!
It's a worthwhile journey you have started, good luck with it all.
Best Regards
Greenage
