Works great
Scent Name: Berry, Size: 100 Count
I have to use these for about 1/2 a year. I keep bronchitis and sinusitis from about Oct. to April every since I was a child. When I am suffering with these I can't breath through my nose, epically at night while sleeping and would wake up several times a night with dry mouth so bad ir was literally painful. My mom turned me on to these because she was using the with her CPAP. I sometimes have a bit of difficulty getting them to stay put but overall they are great. I have tried the OG, cinnamon, and berry. The OG have no real taste, but you wake up with a sweet taste in your mouth. I tried the cinnamon because I love cinnamon and didn't listen to the reviews stating how strong the flavor is, big regret, it's like putting two or three fireballs in your mouth, won't be making that mistake again. The berry ones are actually best in my opinion. They have a light berry flavor that isn't overpowering, isn't quite as sweet as the OG. Whichever one you choose you won't wake up in pain. I do suggest using only one at first as opposed to the two they recommend, unless you like waking up with your head on a water logged pillow. One generally gets me through the night unless my congestion is super bad, then I will sometimes have to use a 2nd one about 1/2 way through my night when I wake up for the bathroom and realize it's already completely dissolved.

A Great Product!
These tablets are inspired! I use them every night with my cpap. The back of each tablet has a coating that, when moistened, is easily glued to a back tooth to slowly dissolve while sleeping. Works like a charm! These would be good to use when speaking publicly, too - no more performance dry mouth. You really can't tell it's there once it's glued in. The minty flavor is there, but not overwhelming. I am never without my Xylimelts!

Perfect for dry mouth!
I suffer from extreme dry mouth due to sleep apnea and side effects of medications. I used to gargle with mouthwash made for dry mouth before going to bed but it would wear-off by morning.. I’d awaken with severe cotton mouth! What’s worse is my mouth gets dry during the day when I’m out and can’t gargle. It’s so bad I can barely talk! Thank goodness for these melts!! They are GREAT! They stick easily to your gums or roof of your mouth and stay there! They slowly dissolve over night and I wake up without cotton mouth! I keep some in my purse for daytime. They’re better than lozenges or hard candy because they’re discrete. You don’t want to give a speech and be seen sucking on a candy! I use them so often that I was THRILLED to find them in the 100 quantity bottle at a lower price than I could find anywhere else! Protect your oral health and get these pleasant mint tasting melts for your dry mouth!

No more dry mouth at night!
These stick to your gums and keep your mouth moist all night. This makes it easier for me to sleep. I got them on the recommendation of my dental hygienist and have been getting better checkups since I started using them. It keeps your mouth moist which retards the growth of germs.
