Thanks for your answers people, it's SO annoying when you're not the snorer but you feel guilty for getting so angry as they can't help it and are oblivious!!
flora, I used to feel guilty but not any more as it is me who cant sleep, he is completely oblivious. One night it was so bad I came down stairs and went on AB at 2.30 am just for the distraction and I could still hear him. I swear the walls were vibrating.
