Getting some blood and still run down

Dad is still having problems with his energy and his stomach. This morning, Dad was getting some blood, and they weren't sure if he would need to have one or 2 more transfusions. He is still getting Imodium, which is really working. Dad got little sleep last night, so they gave him something to help him sleep, except now he talks in his sleep and doesn't make any sense. Mom is concerned because he had such a bad reaction last time he was hospitalized with sedation. She talked with the oncologist and they agreed he would get Tylenol for pain or headaches and would not give him anything for sleep if they could avoid it. Dad still isn't hungry- which makes him very weak. No plans to discharge him home today.
