I've actually done this from day 1. I just kinda thought everyone did it.
This sort of ties in though to the "Mouth Hit vs. Throat hit" thread that's somewhere around here. Some people not only don't do this, but they don't even allow the vapor to fill their mouth before inhaling it. You can suck the vapor straight from the e-cig into your lungs with no stopping at your mouth. It's quite harsh in my opinion. Requires me to take some breaks between big puffs. For the quality of the taste though, I prefer the "Tongue/Mouth Hit" every time.
