Suez - I know it can be so frustrating being a caregiver and you certainly have been a good one with all you do for Ron. It still has not been that long since the end of his treatment - so maybe things could still improve. When my son was recovering, he was not always "accurate" about his meds or his intake of liquids or food. That's when I started keeping a spreadsheet on meds and everything he ate or drank and posted a copy on the refrigerator for him to fill in. That way I could show him what was really happening (and show the Dr. too). Also, you need to think about and care for yourself, so that you can keep your stress level down and your happiness level up.
