What type of e-cig are you using?
I wasn't able to quit analogs completely without a decent pv. I managed to get down to 2 analogs a day, but until I got my ego and decent juices it was a terrible struggle for me.
Once I did get the upgraded battery and decent juice (I did start at 36mg, but I am now down to 18mg/ 24 when really craving nic), I made the switch in under 1 week.
It is still a little tricky, but I have 2 boxes of analogs here and haven't had one in almost 2 months, it can be done - good luck! <3
