i agree it was probably a combination of things. one of the first signs of nicotine poisoning is nausea. gawd awful nausea. i actually got that from a piece of 4mg nicorette one day. it was so bad i had to spit it out within about 3 mins as soon as i realized what it was.
now when i get the slightest nausea (rare) i put the ecig down for a break or lower the nicotine.
they could have checked your urine for nicotine to confirm it i think.
i do get shortness of breath with higher nicotine levels. thx for the dehydration reminder. i bet that's what's happening. constriction of blood vessels from dehydration. if i can lick that symptom, i'd be happy to vape for the rest of my life, but it's enough to make me want to quit
vaping in the near future.
maybe i just need more water
