So... I've been smoking between 4 cigs to a pack a day (very rare though recently). I used to smoke high nicotine content cigarettes: MB Blacks, Reds, 27's, MB Menthol, NWP Kings, and my favorite, Parliament Full Flavors. I'm also quite certain that the way I inhaled, combined with the speed I smoked them in, resulted in more nicotine than normally obtained from an analog. The reason why I bring this up is that no matter how much 12mg juice I vape, I still have the feeling of nicotine withdrawal. I read in a guide that 12mg was about half a pack a day smokers (my average). Should I have tried a higher content? I do know for a fact that I am quite resistant to high dosages of nicotine, but I'm unsure as the whether I want to quite smoking altogether or continue vaping. This is the reason I didn't get a higher mg content.
