Did someone actually quit smoking after using a vape?

I did but it wasn't easy and required a lot of self control.

I started with a 6mg fluid in an 80 watt device, using a bottle of 0mg fluid I titrated down to 4.5mg, then 3mg, then 1.5mg,.75mg and so on until there were only trace amounts of nicotine left.

At this point I switched entirely to the 0mg fluid for a few days until it no longer felt like a compulsion to reach for it, the addiction having been suppressed.
