Throat and Nasal Sprays, Nasal Strips and Nasal Rings can cost USD$6 - $20 and can be obtained over-the-counter at drug stores and/or pharmacies. Some have herbs or something to moisten to lubricate the back of the throat and nasal passages to prevent snoring. I like the idea in theory. My nostrils tend to close when I sleep, so I turn onto my back, mouth opens and out comes the snore cycle. The sprays have not worked for me as yet either. What doesn't work for me, may work for you. It's an inexpensive option to try.
