All the above advice is good. If you look up my posts you'll find one where I mention that I got second degree burns on my tongue and throat for blu cigs. If you think you burned your throat, see an ENT to verify. If the catty, atty, whatever you've got at the end of your battery is getting hot, and the vapor is getting hot, no matter what, you stand a good chance of burning yourself. Electronic cigarettes are their own beast, and it's in your best interest to learn HOW to vape them. In my case, not believing I could possibly burn myself, it wasn't until after, that I finally realized the vapor that was coming out kept getting hotter and hotter as the vapes were longer and more repetitive, in effect, counteracting the benefit of a battery auto shut off. Of corse, this may not be what's going on with you at all, then again, it could be. By the way, I've had hot juice spit out into my mouth from a boge carto at high voltage, because of the aggressive if not gluttonous (I admit) way I was drawing on it rather than taking a slower more deliberate draw which works so much better with electronics vs analogs.
