Have you possibly tried sleeping with those snore sticks? I can't remember the name of them, but they are the same thing the football players wear on the bridge of their nose before a game, opens things up. Now they come in little packs at the drugstore, they are a bit spendy, but I know that they work to clear up sinuses and when you have colds or if you or your partner snore? Might be an idea to check out, I have worn them and they do work. Gave me a better night's sleep anyway.
