Have not been riding much of late

Sometimes it is hard when your parents get old and have medical problems. It is August 9th and I have only been out riding on three days. Dad has been having dizzy spells, he does not understand why, actually he just does not listen to what his doctors have told him. His doctor told him that he must drink at least 4 8oz glasses of water to prevent dehydration. He tells her he gets plenty of liquid, because he has a cup of Coffee and glass of orange juice at breakfast, an ensure at lunch and a glass of wine with dinner.  The doctor explains that this is not water and it is far less liquid in any case than he should be drinking. She also explained to him that dehydration can cause dizziness. He will not drink water no matter what you tell him.
Second he tells his doctor he is loosing weight, she asked him what he was eating, he told her and she was shocked as his average caloric intake is about 1100 calories where he should be getting about 2100 calories.
She told him to eat more and the people that are undernourished can become dizzy quite easily. He tells her he eats as much as he can or he eats until he is full.  The doctor suggested that we add two ensures to his daily food intake. Well guess what he will not drink the extra ensures always has a reason why not to drink it and there is no point in trying to convince him because that only causes stress. His heart doctor explained to him that worry will cause stress and stress will cause dizziness. He told her I do Not Worry about things and I Do Not Have Stress. He was so angry that he started to cry. His heart doctor told him that what was happening at that point was stress. He stood up grabbed his walker and stormed out of the room. Thanks for letting me rant and rave, it releases my stress :)
