Here's my story. Up 'till now (with the introduction of this cheap, crazy powerful thing called eleaf istick), most people started out on ego-c/ce4 clearamizers. Believe me when I say, you've started out on a whole new level! You've skipped at least two levels. The awful, weak, unsatisfying cigalikes. And the relatively simple, starter kits with ego-c's and simple, yet pretty smooth ce4 clearamizers (or ego-c threaded tanks).
You got yourself a powerful (possibly too powerful, since it puts out more power than it shows, and isn't capable of going any lower) Advanced Personal Vaporizer, and a pretty complicated, very advanced atomizer tank. That's a huge learning curve to overcome. Most have enough trouble starting out the previous way. So, you have a huge advantage that wasn't available to anyone until now. But a lot to figure out, quickly!
This part may or may not have any relevance for you. Everyone seems to be different. When I started out, with the ego-c's, 18 mg nig was too much to handle. It was too harsh, and made me dizzy (50/50, higher VG will be smoother, and have more vapor). So I went to 12 mg nic. that was much better. Of course I wanted tobacco juice. Something equivalent to what I'd smoked. I've gradually increased to 18 and then 24 mg nic, and moved to more dessert juices. I have no intentions of eliminating the nic. I just do what seems good to me. But, I haven't smoked in over 15 months, so, I figure it's all good!
Better quit while I'm ahead. lol. Or perhaps I passed that a long time ago. There's been some good advice on this thread. So just keep on trying. You could always get a few ce4 ego-c threaded tanks and play with them. Just to get some comparisons. They're fairly cheap. Good luck.

p.s., I'd start out on the lowest power setting, and one of the middle airholes. When I turned my isticks on for the first time, they were preset at 3.0 volts. I think that was for a very good reason! Give it a little suck (or two) without inhaling, just to get the coils going, And then suck lightly and slowly, first to mouth, and then to lungs. That is, suck the vapor into your mouth first, and then inhale that same vapor into your lungs. That works for me.
p.s.s., get good quality juices. Nite Life Vapors (can only obtain from PV Liquids), Nicoticket, Halo, Good Life, Suicide Bunny. Alusion, There are many. Do your research on the forum. Brick and Morter store homemade juices usually suck IMO.
