throat hit myself. If i want vapour I'll use penstyle , thats a winner . My ruyan bling has a nice analogue taste and throat hit but exhaled vapour is virtually non-existant. But being a ruyan this is how the original design was meant to be , discreet.
As for throat hit diminishing after a day or 2 , i put that down to getting used to the flavour. I always have 2 e-cigs going , each with a different flavour in and that solves that problem.
