Oh Gawd, not good. Hope you are feeling better soon. Also sounds like you are on a mixed bay, something I still find unbelievable/unacceptable.
I seem to have spent more than my fair share of time in hospital. You can guarantee everytime, there is a nutter in there, who makes life hell for the nurses and other patients in general. It's also the lack of sleep thing that got to me last time, and other people's snoring and other bodily noises, well, it's not good. Last year I spent a few days in intensive care with three male patients in the same bay as me. I have never heard complaining and moaning like it, nor rudeness to all staff in general. But better than that, one of them would regularly light up in bed. Oh yes, all his relatives and visitors kept him supplied with fags and lighters. I did at one point ask why he could not be thrown out. Apparantly he would be able to sue the hospital for negligence if they had done so
