Suggest Medication For Persistent Clear Nasal Drainage

I have a clear fluid drip from my nose...happens very often & spontaneous. sometimes it is one drip & sometimes it just runs down past my mouth instantly. it looks like water but after accidentally getting it in my mouth from time to time, it tastes like tears. I am not sick, have no ear or eye condition. I used to get migraines a lot & this would happen as they dissipated, but now with this dripping, it is not due to a migraine at all. happens when I am standing, moving around, go from sitting to standing, etc. Its been happening since at least early December. any thoughts? I d like to figure out how to stop it as I am continually having to wipe my nose
