I’m sorry you’re struggling! I know some (like me) have issues with anaesthetic making the intestines overly sleepy and slow to waking up. I remember during that step I had a longer stay because of this and was vomiting a lot of bile.
Once you are able to walk more it should help your recovery. I think it feels so much worse when you’re in hospital, hopefully you get to go home soon and progress with your recovery. Wishing you all the best x
