The other inconsistency, and I mentioned this to the nurse when she started accusing me of not having taken care of myself, is that I had been taking tablets for several years, both for my diabetes and for high blood pressure. Yet the first thing the doctors did when I arrived in hospital was to change my meds, to both insulin and new blood pressure drugs. So I feel it is only rational to say "You changed my drugs. Fine. But does that mean I was on the wrong drugs beforehand?"
I mean, my doctor was always a lovely chap, but I have to ask the question.
I hasten to add that I know the answer to these questions is "we'll never know", since we understand so little about the complexities that comprise the human body, and also the NHS's desire to look after its own. But a valid question nevertheless. One that shut this nurse up.
