I hope to help people find what is right for them. I have a free snoring search tool. It will not find products in our site that I am reviewing. There is a list on each product page to show you all the products we have reviewed. Please visit the product page of a product to see what it does. Most of the products I have reviewed are on the free snoring search tool. If you are interested in snoring treatments or snoring research, please visit the Snoring Study Center. Snoring study centers are groups of experts who are working together to find the best treatment for snoring and related problems. Some of these centers include: National Academy of Snoring Research, National Sleep Foundation, Institute for Sleep and Breathing, and National Sleep Foundation. I have personally consulted on a few snoring study studies, and I am happy to provide information on the results. Contact me if you would like to learn more.
The short answer is that it varies. For most people, it takes some time, usually in the form of a gradual decrease in daytime sleepiness and an increase in sleep efficiency.
