I’ve been in similar situations, but not identical. I was able to get most of them off analogs and on over to the vape train. I have a coworker who is having a hard time quitting smoking, and he has purchased many 120ml bottles from me. He doesn’t want to build so he’s trapped in the “gotta buy some more of these things, to put in my thing” game. He’s sub ohming and seems to get to coughing quite a bit at times when vaping. Have him on 3mg / 80v/20p mixes currently. He’s still smoking and can’t seem to give them up and IS vape/smoking. Tried to move him up to 6mg but was too harsh, but 3mg doesn’t seem to be able to pull him over the rails.
We’re experimenting with different mixes, flavors, strengths to see how to get him to where he needs to be. He loves vaping, but just can’t seem to kick the analogs. Guessing I answered your question, as I still sell him juice, and continue to try and find the magic mix that will work.
Honestly coming from a 2pk / day habit for over 25 years, I have NO CLUE how in the hell I kicked them, dripping, with ego batts and ego atty’s. No clue.
