The moral of this story is make sure your battery outlasts what you are going out to do -- and after vaping for 3 months now when I smoked the other night I realized just how disgusting it really is.
I'm fairly new at this (smoked my last cig on 6/28) and that's my current phobia: that I'm gonna be out somewhere and run out of batteries, cartos, whatever. I know that it wouldn't be more than an hour or two before I'd be trying to bum a cig off someone, even though I have no desire to smoke as long as I'm able to vape.
