Most terms in vaping sound crazy haha
The easiest way to describe it is think about drinking water through a straw... You take the water into your mouth (vapor in this case) then swallow it (I'm not helping this... hahaha) that is the mouth-to-lung technique... similar to smoking a cigarette.
If you can not change any power settings on your mod (battery) then I would try a 1.8Ohm coil. It may help with the flooding because Aspire's coils usually run a bit higher than what they say. So a 1.6 may run as a 1.7... and a 1.8 can run up to a 2.0Ohm. Either way, if vaping is helping you for your smoking cessation goals, You can always invest in a new mod. There are a lot out there that will let you change the voltage (or wattage) depending on your setup.
Hope this helps in some way
