If you snore, you are not only keeping your better half awake, you are also not getting the full benefit of a good nights sleep.
I would suggest you look at the Velumount before investing in a machine or other "gimmick".
My wife was having problems sleeping due to my snoring. My doctor suggested the Velumount system. I was skeptical, but willing to give it a try before looking into more drastic measures (surgery, etc.). It took a couple of weeks to get used to it, but now (about 3 years later), I can't sleep without it.
It keeps your throat open so that you don't snore. In my case, it has also helped me stay more healthy - since I starting using it, I have suffered a lot less colds and other respiratory problems. I don't know if this is due to a better air circulation in my throat or just that I'm getting a better nights sleep, but I certainly appreciate not being sick very much!
The company was started in Switzerland, but they have an English-language website (focused on Australia, of all places): http://www.velumount.ch/de
