Snoring Cures

Does anyone know anything about snoring cures? My girlfriend is now cursing me under her breath as she never receives any sleep and drives her insane to hear my nose rumble throughout the night.

Or when I fall asleep on my amazing chair from Ikea.

And don't tell me to try Pure Sleep. I already tried that and that made my jaw sore. I lost many hours of sleep from that.

And those Breathe Right nose strips do not work either.

Does anybody have any ideas?
