There are definitely some people here who have gotten to zero. I plan to but am just up to the first step down - I started on 16-18mg and I'm now on 10-12mg.
1. I have good performing ecigs that meet my needs and enough equipment to never be without
juice or battery (well the M401 is more a good tasting ecig than a good performer, but it was my first)
2. I don't vape constantly - that let me vape more when I lowered my nicotine to smooth over the transition
3. I bought a lot of juices to do it but I figured out what kinds of juices satisfy me (for me it is Turkish blends, caramel tobaccos, vanilla, chocolates, fruit teas)
4. After needing
tobacco juices with good hit for the first 6 weeks, I go to where I had some other flavors with less TH that I could vape and be satisfied (Like BWB Vanilla Bean which has a cool throat sensation)
When I was comfortable on my current level and had plenty of
juice to last several weeks, I started only buying juices 1 step down in nicotine - both my must-have faves and some new ones I really wanted to try (so 10-12mg juices instead of 16-18mg).
Then on a Saturday I boxed up my 18mg juices separately, and brought out the 12mg. I vaped a bit extra and it worked fine. That was a drop to about 75% of my previous nicotine. For a bigger drop like 12 to 6 (a 50% drop) I may phase in the 6mg at times when I vape the most and then go to all 6mg? AT some point I'll buy 0 nic of my faves and of some good mixers and cut down my old juices to whatever my current level is.
The drop in TH is what I miss the most. But caramels and vanillas with cool throat feel and aromatic flavors need to fill in for that somewhat. And some of my tobaccos still have some OK TH at 12mg (yum Casablanca in a carto). I will be OK. I was a lights and ultralights smoker. Some might need PVs that can use LR parts for hotter hits to replace the loss of TH when you drop lower the nic.
