I didn't have IMRT and am not sure if I have any saliva back. But I am grateful that my situation is not so bad as imagined since I need not wake up during the night in search of water. I need not get a humidifier at my room. I have to take a bottle of water with me when I am out but I only drink occasionally and when I am back home, the bottle is usually half full. But I do rely on sugar free candies and chewing gum. They help me a lot especially when I need to talk.So be patient, it is a matter of adjustment and acceptance.
Karen.
