So you have tried everything to stop snoring? You may want to give SnoreCoach a look. It is a smart wireless device that attaches to the back of your t-shirt and combines with an app for your iPhone / iPad to guide you to sleep in a position that reduces snoring.
The gadget gathers data about snoring patterns and sleep position to coach you. It records your sleep and uses a slight buzz when you are snoring to turn onto its side to eliminate the problem. The product is getting funded on Kickstarter.
