Zicam is what I was going to mention. There used to be a TV commercial for it - the bride felt a cold coming on and Zicam saved the day

Anyway, I keep it onhand and use it when I first feel like I am catching a cold. It is a Zinc nasal gel. Maybe worth a try.
I get mine at Kroger but have also seen it at Revco. It is about $10.
