Kevin, I also tested the spray, but I had already devised my own spray, which I liked better.....and still do. I keep a small travel-sized bottle of the regular Biotene mouth wash by my bedside, and another in my purse, and I give several sprays for good relief. The flavor is refreshing, and it works for a while. It might not be quite as long-lasting, but it was more pleasant.
I'll try the spray that they are offering, but I am betting that I will like my own invention better!
