Mine vary from just bloody boogers to dripping this-will-require-more-than-one-Kleenex, if I'm lucky enough to be around Kleenex when it happens. More often then not, I'm just holding my hand under my nose as my palm fills with blood. Nasty!
They tend to happen in the winter, when the air is dry.
Anywho, I'm getting sleepy. This diurnal nonsense is tough. I miss being nocturnal...
