Very annoying but I assume most of the time it just cannot be helped. My ex snored consequently loud that I could not sleep using him. No matter what part of your house you were in you could listen to him. It was a pain in the butt, NO actually in tonsillectomy and adenoidectomy.
My fiance breathes noisily while sleeping some times but the only way this individual be quite is if i struck him because i cant sleep sometimes he would wait till am sleep however i still love him.
