I drink 60ml of 18mg juice a day and I'm in the top physical condition of my life.

No, not really. But getting a little bit into your mouth isn't a big deal. Nicotine will tell you when you've ingested too much, either through your skin, into your mouth, or into your lungs. You'll get nauseated. Like I did when I smoked my first cigarette in 1965, like when I used to quit for like a month and then smoke four in a row, and when I did 2 weeks ago when I went from 6 months of vaping zero-nic to vaping 18mg.
