I can empathise I get them too Suze, though thankfully rarely.
Well, the gut feel I had for dads deterioration was right, he was taken into hospital Friday night. The doctors have been very straight with him, basically he is on borrowed time. They are very slowly draining the excess fluid from his body so as not to overly exert his kidneys or heart, he is likely to be in for a few days. Unfortunately there is no long term solution and he has agreed a DNR when the time comes. Both are frightened and drained emotionally, and dealing in different ways, dad is snappy with everyone, mum us talking about when he gets better. I'm going down tomorrow instead of next week, no sure how long for.
