Sorry to learn you’ve Something Wicked coming your way. My best recommendation is a bit of Mentholatum about the nostrils immediately prior to bedtime; does wonders to keep the breathing clear overnight.
And NOW here’s something you’ll REALLY like:

I use the Vick’s and/or Mentholatum on my chest as well as my sinuses. I don’t use it around my nose at all, as I find putting it on the sinuses is more effective.
But I can’t use the high-falutin’ stuff that other people can use. My body doesn’t like them. For example, NyQuil turns my brain to gray lint for 24-36 hours after a dose. I hate not being able to function.
