I got a neti pot, haven't needed to use it yet but I saw one so got it because I have heard many great things about them.
I don't know where you live, but here you have to get the good decongestant - psuedoephedrine -- products behind the counter and sign for them (because it's used to make meth). The stuff on the counter uses a substitute decongestant and it's useless!
I rely a lot during colds on the nose spray antihistamine, because it WORKS. I get the 4-Way, because you can use it every four hours. I know you have to be careful not to use it too much or too long, or it will make your runny nose worse instead of better. But it helps me SLEEP, not because it makes you drowsy like antihistamine pills but because I can breathe.
Oh, and I find massages help, too! Treat yourself!
That's my advice!
