Hi, just read your whole thread and wanted to wish you luck in your transition and your fight against CRF. My 16 year old boy is battling CRF too, and I know how draining it is - physically and emotionally to fight this terrible disease. I apologize if this has already been mentioned, but some of the symptoms you recently mentioned are symptoms of low potassium levels. Without follow up blood testing you cannot give potassium supplementation, but renal food is high in potassium if you can get him to somehow eat it (Flortification?) and might help.
