I'm prone to panic attacks... and I had something similar happen. I believe it was due to nicotine. Its easy to vape too much because there's none of the other negative sensory experiences- especially the heavy stenchiness.
Years ago I could stomach a lot of nicotine but now, actually.. I only like a little bit of it (12mg or less), and I don't inhale as much as when I was younger smoking cigs and then, dipping snuff.
I've been trying to pace myself by keeping a 0mg nicotine cartomizer around for those times I want the physical sensation of smoking but don't need the nicotine.
