Thanks to all. The Family Dr did blood tests due next week. The urine test showed that he is dehydrated. Hopefully, he will be able/willing to drink Gatorade and they suggested the BRAT diet. He has the problem of not being able to keep anything down but ever since RT he won't (refuses to) eat any food that tastes bad OR even leaves a bad taste in his mouth. The RO told him once that he had to live.
