All these clear-eyed people astonished by snot lately. I truly live in America's lowest-air-quality metro area. Snot continually coming out of your nose, steady, not dripping, in strings up to four feet long, all day and night, from February to August, is normal.
Welcome to BL, party girl. I think the runny nose may just be from a nose that's a bit sensitized. It'll go away if you keep assaulting it with more blow, and come back after you take a long break. If it's clear snot, it's just a reaction. Yellow and green could mean an infection. Red just means you've been going a little too hard lately. Also, use the "quote" button if you're replying to a specific poster, and try to keep all your thoughts in as few posts as you can.
If any of you coke users have tried meth, you know how it burns. Sometimes like someone rammed a red-hot screwdriver up your nose, through your sinus, into your eyeball. It naturally slows people down on the redose.
Intense, localized vasoconstriction causes some of that pain. It can cut off oxygen to your nasal tissue, causing it to die and eventually slough off. And it happens the exact same way with coke snorters, they just remain blissfully unaware of the damage thanks to that fantastic numbing action.
So listen to the blood and skin and nervous tissue in your morning-after boogers, coke heads. You didn't feel it, but your nose was screaming in agony. You definitely wouldn't have done fat lines every twenty minutes all night long if you could feel the burn you were inflicting.
(I've started to wait a couple minutes between nostrils, at least with meth, to let the effects from the first line subside before attacking my septum again from the other nostril. I have no idea if that's a waste of time or not.)
