To stop snoring, try sleeping on your side with a firmer pillow instead of sleeping on your back.

Snoring is caused by a narrowing of the airways during sleep. When we sleep all our muscles including those in the throat and neck relax. The problem occurs when the muscles relax too much causing them to flop around and block the airways. Sleeping on your side and using a firmer pillow avoids relaxing your throat and narrowing your breathing airway.
