They may have saved my life!
These are fantastic for people with dry mouth! They have been a lifesaver for me. I HIGHLY recommend them to everyone! I carry them in my bag as well. Thanks to the one who invented them. I feel normal again!!! Easy to pop in mouth and they last overnight too.

Save your money......
Size: 1 Ounce (Pack of 1)
I had high hopes for this, but sadly, it fell short. I have to wear a CPAP mask at night & the dry mouth is just one of the things I hate about it. I saw this, read the reviews & decided to give it a try. I used it per the directions, but it really did nothing to alleviate the dry mouth. I'm giving it 2 stars because it doesn't taste bad, but that's the only good thing I can say about this.
