It's rather annoying that the only actually effective nasal decongestants are amphetamines or otherwise closely related compounds. Sudafed is great for daytime relief, but there really is no good sleep time decongestant. Sure Nyquil is a thing, but it just relies on the antihistamine to produce drowsiness without any actual decongestant effect. And Dextromethorphan is arguably even more useless than Phenylephrine since at least the latter could conceivably be effective if you shot it up.
