When I quit smoking I'd never heard of AVRT but I applied the same principle of vowing never to smoke again. This isn't so surprising because AVRT formulises the lore of how people have always self-recovered from drugs.
My case was different from yours in that I was a chain-smoker - I remember smoking once with my head up a chimney in a house where smoking wasnt allowed - which actually helped by giving me a big motivation to stop.
If you want to quit I dont see why the approach you outlined wouldn't work.
I used nicotine replacement therapy which I now wouldn't advise because all that is is a safer form of smoking and my quitting smoking involved giving that up as well. It really was just means of prevarication suggested by my AV.
Some years later I still have occasional AV about smoking. It's most intense in dreams where I've started smoking again and I wake up thinking 'oh no!' and then feeling tangible relief when I realise it was but a dream.
