Take a straw and plug one end, and try sucking on the other. That's what my e-cig is doing, and now my lungs hurt from the strain of sucking harder to get any vape from it. I'm sure I know what's wrong with it, I need to clean the atomizer. The part that sucks is I've only been using it for a couple days. Really? I have to clean this thing every couple days? I was under the impression that cleaning them would be a weekly thing? I just started this whole vaping thing and only have the two atomizers that came with the kit. This sucks
