I'm new to this whole thing. I just got a KGO, and am using 18mg strength. When I exhale, the back of my throat and back of the roof of my mouth burn and sting. It's not terribly painful, but it is undesirable. It seems to differ slightly with different flavours, but all have the same strength nicotine. I'm used to smoking menthol lights. I'm usually a pretty deep inhaler, and vaping on the inhale is fine, it's the exhale that I haven't gotten as much pleasure from. But, is this burning/stinging sensation in the back of my mouth/throat what throat hit is supposed to be? If I want to lessen this, what do I want to increase and decrease in terms of PG and VG? Thanks.
