I'm actually the opposite. I started nicotine intake in the form of cigars and dip, then went to hookah. I never really smoked cigarettes, but my fiance did. We tried quitting, I was, for the most part successful, she took a long time but still craved. So, we took up hookah. Cause of the nicotine level in cigars, it takes me a lot to get the calming sensation of nicotine. I started on 12mg, chain vaped for about an hour and a half before I started feeling it. I recently just up'd to 18mg, and it's still taking some chain vaping to get calm, but only around a half hour. I found that starting on 18, then moving towards 12 of another flavor helped with the TH and the affects. Finding that happy median takes some time, and the TH takes some getting used to. Heck, my brother has been smoking for almost 7 years, and at one point was a 2 pack a day guy (then he moved to Alaska and could barely afford a half a pack a day) and he still coughed from the TH of a 12mg! Thing is, you decide if you want to take the jump down or not, but I suggest keeping some higher stuff around just in case.
