Yesterday, on break at work, I got my first shot of ejuice in the mouth. It wasnt THAT bad, the juice actually tasted good, but it was still unpleasant. My tongue went numb, I had a slight headache for about an hour, and I felt a bit dizzy. Im fairly certain I know what I did wrong. When I refilled my eVod the night before, I failed to check and make sure that the atomizer was screwed down securely. The upside is that Im unlikely to make the same mistake again. However, it does make me wonder how frequently can I expect such things to happen?
