Hi, Diane
Paul is doing really well to have worked so far into therapy.
My husband was exclusively on liquid nutrition at that point. He found that standing up at the sink made it easier to gag down the shakes. It was distressing to watch, so I didn't. The magic mouthwash and viscous lidocaine helped him. If he is not able to get enough fluids in by food, IV fluid or a PEG or NG tube will be needed. Remember that dehydration will make him feel worse - a bag of fluids helps immediately. For the radiation burns, he used peroxide soaks and Silver Sulfadiazine cream.

The upcoming week is going to be pretty sucky, and probably the week or two after therapy, but it's its nearly the end; you will both get through it. I found that meditation/breathing helped me.

Virtual hugs to both of you!
Maria
