Breath-right strips are worthless for most snorers. In my case, the snoring came from the soft palet in the back of my throat, not the nose. And I'm skinny.
I had surgery to remove part of my uvula. The procedure involved cutting off the end of the uvula and using a laser to burn part of the surrounding area. The remaining scar tissue is less prone for vibration during sleep. The snoring isn't gone completely but it's quieter and less frequent. Overall it was worth it.
