Dinah,

Eric had a CT scan of his lungs and all looked clear. He hasn't had any additional scans other than a CT scan on neck/head and lung. He has not has an MRI or other imaging. Do you think some of those are necessary/helpful?

Thanks everyone else for all the tips. I am writing them down and taking notes. I have a list of things to buy (good blender, humidifer, Biotene Mouthwash) and all the suggestions are great. Thanks!!
