I went from a pack and a half of reds chain smoking to zero smokes from day one. year and a half now and also found myself going from chain vaping to easily going without if need be...
the first or second week I got caught in the field with dead batts and bought a pack of smokes, lit one, found it disgusting and chucked the whole pack.
Sometime a few months back (not sure exactly) I bummed one and lit it just to see..... uggh.... chucked it as well after 2 puffs....
I have significantly reduced the vaping with MBL snus mild and spearmint while at work...
