I've really been trying to get on this gaping train. I smoke less than a pack a day and have bought the eleaf mini along with the gs16s tank specifically for the mini. I have bought several juices from Vape Wild ITCVAPES Mt Baker Vapor and from my local smoke shops. I recently upgraded to the istick 30w and have kept my eleaf gs16s tank and I'm using it on the 30w. My problem is every time I attempt to vape for the day I wind up weepy coughing up phlegm and heavy chest. I don't understand it. I've done 50/50 juice higher pg juice higher vg juice 100% vg juice...what am I doing wrong?? Anyone with advice please help as I sincerely would like to put down the cancer sticks.
