Finally learned what a true dry hit feels like :(

So I just moved up from a subtank mini on my Kbox Mini to a velocity RDA clone, and I have a dual vertical coil build at .3ohms. I juiced it up and then took about 3 nice long draws on it at 40W and on that 3rd draw it felt like someone stuck a burning steel rod down my throat......i thought i was gonna die. Just thought id share that with y'all.
