I wake up in the middle of the night with both a runny and blocked nose. no meds to take. what home remedies can i use?

Check environment: I'm guessing something is present in your bedroom you are sensitive to. Start by doing a 'mega-cleaning' to your bedroom. Get rid of things that trap dust, cover your mattress and pillows with a completely enclosed vinyl casing before the linens go on, and make sure you wash bedding at least twice weekly. Try saline rinse and neti pot (both available over the counter) when symptoms do occur.
