So, I sometimes over fill my cartos. I know, I know, at this point you'd think I'd have figured it out! Well I have, I'm just a push the limits type and that's that. When I get the inevitable mouthful of ejuice, if it's more than just a tiny bit. Say, a couple 3 drops. If I swallow it, I get the hiccups. These are some every 5 second, full on hiccups! I used to get this with nicotine gum as well. Anyone else experience this? Anyone know why this is? Just curious.
