This seems to be the crux of what you are saying. I actually think the opposite is true. We all want to be happy and if we think though the very good reasons why we want to quit, we will be happier when we do quit. If OTOH you quit because you believe that you have no other choice then you are quitting or even quatting under duress and this does not seem to me to be a sustainable state in the long term, that is, thinking that quitting may not make you generally happier - of course there will always be times of unhappiness - is AV because it makes it more likely that you will return to drinking again. IMO of course.

But anyway, why if thinking through the reasons why you want to quit makes quitting a happier experience would you not want to do it? You can of course just quit anyway but isn't it better to be happier about it than not?
