I like to locate the basket or CU to provide about ¾" in the chamber and fill it loosely, maybe 2 pinches or small scoops. I've used all sorts of heat settings; that's your personal choice. I'll click it, hold it to my mouth, and when it vibrates, start my draw. I like to stop after a bit and exhale through my nose to see how the vapor production is going and once I know that it's started, I commence my real inhalation. I'll usually count slowly to 8, turn it off, but keep inhaling until 12, then pull the tube and finish the draw. I really recommend a j-hook or glass of some kind. This lets you use it upside down, and cools the vapor sufficiently. I used to cough quite frequently but I hardly ever cough anymore; some techniques you just have to pick up through experience.
