The patches seem to help some so far. He does notice the difference if he forgets to put on his patch. I would definitely have your husband ask the physician for an order if he can. I do know that Frank has to spray his mouth with water due to dryness more often now. He is also been on a feeding tube for over a year now and he will always have to be on it. The doctors are still amazed he's been cancer free for 24 years now, unfortunately all the late/long term side effects have really affected his quality of life. Yet, he says he is grateful he is alive.
