I'm using a 50w eleaf battery, Atlantis rebuild able tank, and a 30w coil. I have been vaping for two years, started at 30 mg nicotine, but got all the way to 1 mg. Then it's too harsh. I can't puff it without coughing. Right before the harshness I changed the coil and refilled the tank with a new bottle (always from same shop, they know what I like). Took juice back to store and they re-did it, still too harsh. Changed coil (about 9 times now), still too harsh. Redid juice again, changed tank, changed battery, changed tank (again), messed with wattage (before was always 3.8w) found that if I purchase a 30w coil rather than my usual 50w it is not as harsh (can puff twice before I'm coughing up a lung versus the first puff on 50w coil). Messed with air flow over and over. I'm feeling like the vapor shop bought some new PG that's too harsh. The smoke has been less than what it was too. I have asked them for help each time I changed liquid. They told me to let more air in, which does create more smoke, but still just too too harsh. Then they said to turn my battery up...I have been doing my method for two years-two years..I don't think it's suddenly where I put my battery at!! But now I'm just smoking and I really want to let them go again. Any thoughts, ideas on what the problem is??
