My husband is uncharacteristic ally quiet, not communicative. He has a lost blank look but is functioning. Driving down the middle of the road, forgetting to close drivers door before pulling out, says he only is tired and his back hurts. There seems to be a disconnect between what is happening and his understanding of it. This is not him at all! He is often borderline diabetic type 2, has gout and takes medicine for it, takes a cholesterol drug, a blood pressure drug, and ibuprofen as needed. We are traveling and today was scary. We also are bird hunting and in tick territory. Any ideas?
