Thank you for your reply Margaret. I wish you all the best. Your advice has helped to cleared up my reluctance to ask for help and I will be calling the dietician on Monday. I am not really afraid as kidney issues have been with me all my life. I caught a germ when I was around 3 or 4 that resulted in total kidney failure. I made a complete recovery but I don't know how they did that. Of course this was before kidney machines so that illness should have been fatal. But, a string of incredible coincidences ever, and the skill and courage of the team of medical people saved me.
