So i have been vaping for about 12 weeks, cigarette free 10 weeks. The problem is i go through coils really fast. If i am lucky a coil will last 5 or 6 days. My set up is a istick power max 80w with a vengeance tank that i run at 35w. with juices 60vg 40pg. when you factor in the cost of juice and coils i am spending nearly as much as i would on smokes. Anyone have insight as to what i am screwing up!!!
