After I posted the last entry I went back downstairs and lay on the sofa shivering. I covered myself with a quilt (having shooed the cat from his sleeping place) and fell into a deep sleep for several hours. I awoke and had some tea, carried on reading etc and then it was time for bed. I slept well, only waking up at about 5.00.
I got up and showered and now it's time to take my pills before going back to the hospital. All good so far.
