i can answer this one after last year when my appendix burst and I was a whisker away from being in HDU with a nasty peritonitus. I hated being in hospital, for me it was like being at work and not getting paid!!
The machines were bleeping all night! I wanted to turn them off!!, a woman in the next bed to me had an IV running which kept alarming as it was in the crook of her arm, on the second night i kept getting up and straightening her arm as it was driving me nuts! they wanted to catherise me to keep an eye on my fluid balance, i refused telling them it was a lazy way of checking it when all they had to do was measure my bedpans, infact i said me and my family would do it instead if they didnt want to!
on day three, i got up with difficulty, showered, put make up on and smiled at the surgeon lied and told him i felt fine so he would discharge me, which he did, I was glad too as by then the other patients were asking me to do things for them after cottoning on i was a nurse, even though i had just had abdo surgery myself and could hardly walk!!
When i got home it was such a relief but i really felt ill, and ended up with a nasty wound infection from the peritonitus, wouldnt go back and eventually got better after 4 courses of oral ABX
the answer for me is that although i behaved i hated it!!
