What flavor? I certainly get that tingle in my throat with the Strawberry Lemonade, but isn't that what lemonade is supposed to do?
Anyways, yes right out of the package I've had some flavors hit my throat a little rough, I just turned the wattage down a bit and it was fine for me (been on 150w with my tank/coil lately, drop it to 125-130w and I'm solid).
I vape the 6 on nicotine and the dripper 80/20 vg/pg blend (I have huge juice holes on my tank's coil so not a single burnt hit since I've set it up).
For me the Strawberry Milk and Honey Milk (my 2 favs from them) are super smooth. The Blueberry Custard I got yesterday was a little harsh out of the package though. And the Cinnamon cereal one tickles a bit but I think that's just the cinnamon. Anyways, let them sit a week, shake well, and try again. My stuff that's been sitting for two weeks is all very mellow other than the Lemonade, even the Cinnamon is a slight tickle, not make me want to cough tickle.
Not saying you won't still dislike them, but the overall palate does change after a week or two.
