Hi ValiI am not comfortable enough with French, Okay?.
I have never smoked in my all (24y)life,
but me dad's been smokin till he was 16' and I know it's hard,
He explaned me many times that
The DRIVE (envie?, desire) TO SMOKIN is BUILT (étayé) on BREATHING SURVIVAL instinct and therefore cannot be 100 per cent suppressed (which would mean death!).
You probably have to RECODE IT
into DESIRE to ENJOY (jouir) LIFE
(any other drive should do).
So don't try to TERMINATE anything,
on the contrary KEEP DESIRING pleasure of all kinds (toutes sortes d'autres)
OK, I give up here, ....but don't GIVE UP QUITTING!!!!!!
Keep cooling warm Vali さん
