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.
