My boyfriends snoring is really effecting my sleep?...

...i have lived with my boyfriend and his family for about three years now. over the last year or so he started gaining weight and now snores so loud and sickly soundly that im up all night with headphones and music. I now have to stay awake all night and when he awakens, i can go to sleep. because of my sleeping pattern im not eating and i find myself sleeping for almost 12 hours.

Ive tried rolling him to his side, and asking him to lay in other positions but lately he just kicks me and tells me to shut up.

I'll probbaly get answers like "sleep in a different room" but since this isnt my house, and i dont want to sleep downstairs on the couch (early risers here ) i really cant go any place else to sleep.

my questions are,

he has never snored up until this last year. why now?
is there anything I can do do stop his snoring?
inexpenissive store bought items i can try?
and can this be from a health problem he has developed, if so, what could be causing it ?

thank you in advance, sorry about the length :)

"Sounds like it's related to his weight gain. Either get him to lose weight or get a new boyfriend.
God bless."
