Here's a suggestion: I suggest that you never rub your eye after handling nicquid. What a rookie mistake! I've been doing this for almost three years, and did it anyhow. [duh]
I somehow got a drop of nicquid in my eye when blowing through a cartomizer to clear out the center. I have NO idea how it happened, but it hurt like hell. I close my eyes whenever I have to blow out stray nicquid now.
