Michaelii, will you be taking Ethyol to help with the saliva? My dad is going through his IMRT and Cisplatin now-he's down to get the surgery you had in June in Sept. So, we'll give you hints on the chemo/rad and you can give us hints for the surgery-deal? My dad noticed that his mask is getting tighter? Does the radiation cause swelling or could it be the fluid shifts for that day? He has had NO adverse reactions to the Ethyol.
