That's a new way of describing something I am sure we all have done. For the most part more vapor is the goal except when you are trying to be sneaky. If you don't use it for a while I would guess the coil is getting good and saturated with liquid,then as you vape a while it does not replenish as fast as you are vaporizing it. Not know what you are using it would be hard for anyone to make a suggestion on changing the situation. Another thing that happens is the battery recovers a little during idle times and the first few hits are at a higher voltage. For more vapor use less resistance coils and or higher voltage for less vapor use higher resistance coils and or lower voltage. Those are only options for more advanced or mainstream devices. The convenience store ecigs are pretty much run what you brung.
