Make sure your mod is at high wattage - I use around 55-60 because that's what's comfortable for me, but it's whatever works best for your mod. Hold the button a little before you start to inhale, and that'll help as well, and what helps a lot is to blow out first and then inhale. Be careful with this though, because if you do this with a high wattage setting then it might get too hot. Definitely get juice with a high VG. Full airflow on your atty, and make sure your pull is strong enough that enough air passes over the coil. Don't keep the vapor in your lungs for too long or it'll dissipate.
