I don't think that much juice is a lot, actually especially at your nicotine level. I would see your doctor though if you get sometimes a wet cough and a dry one.... Not sure that's vaping related, well, yeah, which is why a visit to a doctor might help. You could up your nicotine levels if you wanted to vape less and all the other strategies might help as well. It's possible something in your e-juice isn't agreeing with you, but I am not a doctor.
Good luck,

I'm more concerned with the year for illness as a whole.
I know I had pneumonia already this year, and that's something I haven't gotten since before I started vaping. Took two rounds of antibiotics to clear it up too. My husband, for the second time since we have known eachother, had to go to the doctors and get on antibiotics too here just two weeks ago.
Everyone around here is getting sick, and not just regular sick either, but sick enough to need one or two rounds of antibiotics.
It's going to be a bad year for sickness I think... that makes me want him to see a doctor more, simply because a cough isn't normally associated with vaping, especially such a small amount, and not normal to the OP either.
With nastiness in the air, I'd see the doc first... just in case.
