Yeah I was thinking humidity may have been a factor, but if it was, it wasn't at my house. I have a humidifier that's built into my furnace. Possibly my workplace, but I was content with stopping the Rhinocort if it meant stopping the bleeding. I had a bad post-op experience with a tonsillectomy years ago and quite frankly the slightest taste of blood in my mouth is enough to freak me out! I will have to figure something out soon though because that stuff really did help me.
