So, I take it you're still smoking.
As an ex-smoker I know that now never seems like a good time to quit; there's always something happening or about to happen that makes it the "wrong" time to stop.
You seem very well versed in AVRT but can't, at the moment, commit to a Big Plan because the perceived benefits of smoking outweigh the disadvantages. Maybe you could reverse the balance and build up the necessary motivation by reading some good books on quitting smoking. Something in them might resonate with you and allow you to make a Big Plan you believe in.
Have you read Allen Carr's "Easy Way To Stop Smoking"?
He also has a longer and more comprehensive one called "The Only Way To Stop Smoking Permanently".
There's one by Gillian Riley called "How To Stop Smoking And Stay Stopped For Good" which has good reviews on amazon.co.uk
I haven't read this book but it seems to have similarities to AVRT.
