Would continue to buy again
Size: 27 Count (Pack of 1)
Purchased twice. I wish they made these bigger. Moisturizing mouth well and flavor is pleasant and long lasting. I have Sjogrens and suffer with dry eye and mouth. These work better than regular lozenges.

Dry mouth is miserable.
Size: 27 Count (Pack of 1)
The mouth lozenges for dry mouth were excellent at first, but I have dry mouth all day, and they started upsetting my stomach. I guess I was taking too many. Since I switched to the spry, I don't have a problem. I keep the a small bottle of the spray in my pocketbook, because I need it sporadically. It is probably different with each individual.
