yeah, the morning hump is rough... I use 18 then, 12 throughout the rest of the day. Also like Always said, it really depends on teh battery too... (and the tank you're using), since the triton + triton tank WILL vaporize much better than a g6/ mini/ carto setup. More vapor generally will equal higher nicotine intake.
On my triton, I am fine with the 12mg... if I were to put that same juice in my REO, it'd knock me on my ..... (I use 12mg cut with 25% VG for a lighter kick to the face... I tried Tribecca at full strength on there, and had to go lay down

)
