same exact experience for me. it didn't take long to get the hang of it, maybe a week or two. got my mom to try my ecig, and she ( super heavy smoker ) coughed after her first drag as well. i think i definitely inhale less vapor than i did smoke from a cig, which is a good thing. i prefer having less stuff going into my lungs. with vapor, we absorb a lot of the nicotine through our mouth as well, unlike cigarettes.
