Works well
Flavor Name: Peppermint, Size: 100 Count (Pack of 1)
This is a great product if you have dry mouth for any reason. It dissolves quickly though which to me for the price should last a bit longer. I know there is another product that I use for night time. They see you can last all day which you kinda have a lump in your lip. I will continue to use this product nonetheless.

They work for about two hours, and then you might need to take another one.
