After 30 years of smoking between a half a pack to a pack a day (more or less, depending on what was going on in my life at any given time), I tried my first e-cig a year ago. It was a good alternative, but its inconsistencydead atomizers, battery failure, etc.led me to abandon vaping all of last summer. But about five weeks ago I bought my first bottom feeder and stocked up on juice, cartos, and batteries in order to make a serious go at vaping 100% of the time. It worked. I have not touched an analog in five weeks and I have absolutely no desire to go back to them.
It's all in the choice of PVs. Find one that works reliably for you, make sure you have all the supplies you need to keep you going for long periods of time, and giving up analogs is way easier than one might think.
I don't plan on vaping for the next 30 years, so it will be interesting to see if, when the time comes, I will be able to kick the vaping habit AND stay off of analogs. But I'm feeling more confident of success than ever before.
