Hello all, I'm pretty new to this forum and have a question for you all. I have been smoking my e-cigs for a few weeks now. (Janty Dura and Janty Classic) I recently cleaned my atomizer for my Dura via the boiling method suggested by other members of the forum. I blew out all the excess water and let it dry for hours. I then dropped a drop or 2 on the mesh in the atomizer itself and let it sit for some time. Since then, it seems as though the vapor that I'm inhaling from my dura is causing quite a bit of burning in my lungs, almost to the point of making me cough. I've always had a smooth draw from my dura, never felt like I was choking or about to cough. I was just curious as to if anyone has any suggestions, or possible explanations? I've tried virtually every e-juice I have in the Dura, and they all seem to be having that same burn, with a somewhat metallic taste at times. I'd appreciate any suggestions and or help anyone could offer me. THANKS!
