DR singdaw and George and others still dealing with nasal issues - I remember when I was working on Eleanor down at Ford's Theatre, practically the whole company - except for me! - came down with some sort of pesky "cold". And it just would not go away. Thankfully, it never really impeded anyone's performance or performances, but it really was annoying. The company manager at Ford's went ahead and made arrangements to have everyone checked out by the same doctor just to see if everyone had the same thing. Well, some people did have the "common cold", others, it turned out, were having allergy issues. However, a majority of people had what the doctored labeled as "IPND": Insidious Post-Nasal Drip. -And I don't think I've ever seen a medical condition labeled "insidious" before or since then. In any case... A daily Vitamin-C booster, and a low-dose of Mucinex seemed to help keep things in check and clear it up eventually.
