Hi all. I'm a new vaper trying to quit a 30 yr smoking habit. Bought an eLeaf iStick 100w TC with a Griffin Atomizer. Any tips pls. I seem to be drawing too harshly, maybe too quickly (?) as the atomizer heats and spits. Also cough like a demon. Using Clapton alien coils. Settings on device 42.5W, 0.22ohm, 3.06V. Juice Orion meteorite 6mg.
