I did this a few years back, after about 9 months of vaping at decreasing nicotine levels. pretty much the day I swapped to 0 nicotine I started noticing people smoking in the street, within a couple of weeks I'd stopped vaping, and within a month I was smoking again. Up until this point I had not realised just how ingrained my nicotine addiction was (before this I assumed I was mainly just behaviourally addicted).
