Thank you for all your responses, many good suggestions! We ended up in ER on Thanksgiving day, and indeed it was the Fentanyl patch, the two 25 mg (?) patches suggested. The nurse at the cancer center said that this med is their starting dose! But for Lee he was extremely paranoid and disturbed...So this med is now on his allergy list. It took two days but he came back mentally I'm happy to say.

Luckily, Lee has not had any significant nausea so far, most of his problems were pain from the treatment. The PEG tube is helping him get nourishment and water.

Tomorrow we start the last 11 days of treatment.
