I'm hopelessly addicted to caffeine, I think coffee is harder to quit than analogs, at least for me. 
  
I hope you all are right about nicotine alone not being any worse than caffeine.  I started vaping as a step to quitting, but I love this stuff!! 
  
I started at 18mg when I first got off of analogs, and am now onto 11/12mg.  I just placed my latest juice order for 60ml of 6mg stuff.  Maybe I'll find I'll be happy with 0 nic, we'll see!
