You are chain vaping.....
OK.. so to change your vape style......
Start to drag on the drip tip ( for a half a second to a second), and THEN hit the fire button, drag while holding the fire button for your 3-5 seconds, release the fire button but keep dragging till the air gets cool again ( about half a second to a second).
Hold this in your mouth, for 5 to 10 seconds, if you wish you can bring this to your lung or just leave it in your mouth the whole time, and then slowly exhale through your nose. Count to 10 Mississippi... and then repeat all over again.

Really it sounds like from your description, that you are "hitting" the vaping device like it was a cig. You must understand that it is not!!! The nic in vaping will be far more efficently absorbed through the wet parts of the mouth and nasal passage. Think of technique of vaping more like how one smokes a cigar... than how one smokes a cig.
The reason I am having you drag on the tip for a second before... is to prime the wicks, and to start airflow
The reason I am having you drag on the tip for a second after... is to cool the coil, prime the wick...and clear our condensation (condensation and extra hot coils, cause that burnt crud on a coil faster than anything else)
The rest of the steps are just to allow the "drag" to have a chance to be properly and efficently absorbed, in the belief that if you improve this you wont need to take as many "hits". And to also allow the coil to cool down.

Some additional reading..... The times he list are a bit shorter than mine... but I find better to go for longer times at first... as you are trying to retrain the muscle memory away from the smoking habit... to the vaping habit. Once you have "mastered" it with my time counts.. you will eventually settle into your own... from a place of comfort.. and not of fiending nic need
