Obviously follow
@The Sofa Traveler 's advice above, also get into the habit of Putting the vape tip properly into your mouth 'past the lips' rather than 'on the lips', the amount of times i melted my lips when i first started was silly! Doh!
You can also experiment with the speed of inhale, if the wattage is high breath faster, if the wattage is low breath slower, if you have no control over wattage on your vape experiment with different speed breaths. If you have a vape with Air-flow control experiment with different settings, there is usually an air intake that can be set.
