Mom is feeling better and acting more normally. Her bilirubin and ammonia levels are very high, though, indicating some possible entanglement with her blood stream. That, combined with a build up of pain meds, has likely caused her behavior. I talked to her this morning and she sounded like herself again. She doesn't remember Sunday or yesterday.
Her PCP talked to Mayo about the labs. They're concerned, so they put her on more stuff to get the bilirubin and ammonia out of her. Dad said she slept most of the day and is pretty exhausted yet.
