Hi there, my father, aged 79, has a thirst he cannot quench and had become unable to sleep because of this, he is also feeling pretty wiped out. His GP has sent him for blood tests but unfortunatley his appointment is over a week away. I know a full diagnosis is needed but feel so sorry for him getting no beauty sleep! are there any basic sensible things in can do in the meantime, stuff to avoid perhaps?? I have searhed for hours but feel a bit over faced with information. I have also not noticed lack of sleep mentioned in any articles. Thanks folks x
