They actually make my dry mouth worse.
Flavor Name: Peppermint, Size: 100 Count (Pack of 1)
I got the peppermint flavor. It’s very strong and stings, and they make my dry mouth worse. They are chalky and caused me to cough. There are plenty of cheaper and effective ones out there to choose from… that won’t go straight into the trash.

What's to say, a Saint and a Doctor of the church.
Format: Paperback
Content awesome as one would expect from a doctor of the church. Problem, font size of the printed is to small for comfortable reading.
