My dad and I are in a similar situation to you- terrible nasal congestion constantly interfering with sleep.
The quick and dirty solution is decongestants. However, vasoconstrictors (pseudoephedrine, oxymetazoline, phenylepherine, etc.) often have a "rebound effect", i.e. when they wear off you find you're actually more congested than you were before you took the drug. In this sense they can be quite addictive. I try not to use any unless it's absolutely necessary, and only once every few days at that.
One thing that helps a little bit is Breathe Right nasal strips. They will often open up the nasal passages enough that I no longer have to struggle to breathe through my nose. If I'm only slightly congested, I use these. I don't know if the increased air flow would be enough to keep you asleep or not, but it's probably worth a try.
For the most part, I have pretty much adapted to function on a few hours' worth of sleep. I can go on a three hour nap twice a day for an indefinite length of time. I don't know if that is enough rest to fully clean up the brain, but I don't feel crappy all the time so I suppose it's good enough. It definitely works better for me than sleeping for 6 hours once a day. I typically sleep in on the weekends, but I recently saw an article claiming that isn't enough to erase slept debt accumulated during the week.
