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.

Clean ingredients, actually sour
Flavor Name: Tangerine, Watermelon, Blue Raspberry
Absolutely wonderful! Actually sour and love the ingredients most of all. I can love sour drops again like when I was a kid without the terrible “everything unnecessary added” I bring these on flight trips and when I crave something sweet.
