There is a pesky health issue that snoring causes. Its so pesky that under specific circumstances it can be deadly. This disorder is known as sleep apnea. But essential this is when you stop breathing because there is some sort of blockage in your air way. Lots of people suffer from this. Some well known celebrities as well as regular Joes. A not so regular Joe like Joe Rogan has suffered from this. He documented it all on his website. He was able to get a mouthpiece for sleep apnea pretty easily online. His tongue was causing all types of breathing obstruction problems.
Finding the right mouthpiece can be a bit tough. Not all of them will be comfortable. Some even allow you to adjust the fitment which provides a seemingly infinite amount of opportunities. If you go online you will find some many sleeping aid devices such as machines and chin straps. Your best bet is to first consult your doctor and see what he recommends. No all snoring disorders are created equal. Some might be because of your tongue. Other might be because of oversized tonsils and others could just be from allergies.
Overall this is something you should look at right away. Not only will your wife or girl friend thank you but so will your health.
