I am 26, 9 stone, don't smoke, work out three times a week, don't drink a lot, yet I snore LOUDLY. It's making me really paranoid about sleeping with my new partner. My mother is also slim (smokes and drinks tho) and snores VERY LOUDLY and I don't want to end up being heard several rooms away 
What can I do? I feel like a doctor would laugh at me.
