In my care taking mode, I decided to make Dale go to Huntsman for blood work and consultation with his doctor since he complains of increased fatigue, nausea, and night sweats. Good news: blood looks good, no viral infection, and probably allergies cause his coughs. More news, they will schedule a PET scan to validate that organs (i.e. stomach and digestive system) don't need treatment. Validation news: get some exercise to build stamina.
