"There are several things you can do which help many people. Try the tennis ball trick. Many people who snore do so while sleeping on their backs. Place a tennis ball in a sock and pin it to the back of the shirt you sleep in. Then, when you roll over at night, the ball will nudge you back on to your side, where you are less likely to snore. Also, try a humidifier. Many people snore because of undiagnosed allergies. The humidifier will ease congestion, which will reduce snoring. Whatever you do to stop snoring, it's worth it. Snoring has been linked to a 67% increased risk of stroke."
