This is my third order for this product. I have tried other options (hard sugar free candy, cough drops) and nothing is as long lasting. If you have a CPAP machine, these are indispensable.
My dentist recommended this product. I love it. It works so great or my dry mouth while I sleep.
The dental hygienist gave me a brochure about two years ago, I ordered the Xylimelts and have been using them. Now I sleep all night. Only thing I have found that stops the dry mouth.
