What should i do to make my girlfriend stop snoring?

Snoring treatment: Snoring is the sound of turbulent airflow across nose or back of throat. Typically beathing better through nose, breath right or theravent strips, improving nasal congestion with nasal spray or trying to stay off back are good places to start.

Sleep Study: You should get a sleep study done either at a sleep study center(best) or have your doctor order at home sleep study (as long as it has some form of positional monitoring) to get an accurate diagnosis first.
