Hi, as usual sorry for my bad english
i realise, that you english speaker are really really really high in nicotine than us in france, i was a "heavy" smoker here( 30cigarettes/day). I began with 12mg/ml i and switch really quick to 6 because my french throat need it.reaaly quick.
I realise than nicotine is way more important for the hit, than the rate of pg/vg and the hot or not smoke. (nicotine > hotness > Pg/VG).
Take two juice one with low nic for everyday, and one reaaly fresh with really high nic (freshness like halo subzero hide the nicotine rate for your throat).
And yes you need to have an adaptation time, it's not the same hit than the cigarette, i took 5-7days myself to adapt at this form of hit on my throat.
Have a good day =D
