You can try Dimetapp, which uses phenylpropanolamine as opposed to pseudoephedrin, but phenylpropanolamine is also a stimulant so it might screw with your sleep cycle, too. (But I think it clears the body faster. You'll want the 4 hour tabs. Enough to get you to sleep.)
The reason it's hard to find new decongestants that are safe is that decongestants work through constricting your blood vessels (which is why they raise blood pressure) and pretty much every chemical we know of that's a vasoconstrictor is also a stimulant. (For example, cocaine is a great vasoconstrictor and a cocaine solution is often used in surgeries to stop small bleeds.)
