When I started out, I had similar issues. What nic mg did she get? When I started vaping, I bought 36mg (coming from 1/2 pack per day). My mentality was, "If the nic is higher, then I'll need to vape less, therefore I'll save money on carts!" One inhale, however, leveled me like a truck. Massive swell to the head, and quite the rush. I enjoyed it, yes, and it certainly started me off on a 'bang' and convinced me that analogs were pansy. However, after 2-3 drags, I'd get a headache and terrible jitters. My vision was even shaky, and I'd get quite dizzy. It'd last a little while. I ordered 24mg after that and it was a bit better, but after awhile that even got to me. I've found my sweet spot at 18mg.
