Thnaks guys for all the info. Just wanted to let you know that Rod is moving up his appointment with his ENT just for peace of mind. He wasn't sched to go back until May but because of the sore throat issues, he will go next Wed. Pray for a good report. From what you all are saying it does seem like his mouth is just very, very dry. He buys all these products & doesn't give them a chance. He is very impatient and wants this fixed now. The doc told him he got very little saliva back & that might be all he will ever get. I know it's not me going through this so I try not to be hard on him but I think considering... well, this is a small price to pay. Thanks for all the help again! God bless! Maureen
