I don't know how people use 50/50 with nic. I tried a few friends and it feels like a million tiny needles in my lungs. Then when they try mine they always like how smooth it is.
I much prefer the feeling of seeing a big vapor cloud over the giant sting in my chest, but it really is all about preference. Just like everything else in vaping.
I didn't get the feeling in my lungs, but in my throat and mouth. And it is cumulative for awhile, so that I have to stop vaping until it goes away, or eat or drink something.
I think the increased vapor will be enough of a physical cue to satisfy me in addition to the nicotine, and I'll be able to do without the sting, too.
