For me and i did it, it is as least says just stopping drinking and changing little else. My finances, relationships, health all improved of course but i found myself avoiding all social occasions, opportunities to go places, thoughts of the future were quite negative, angrym regretful of the past, tired all the time (stressed)...stuff like that...
It's a tricky one to define cos i am sure there is a lot people can add but basically, in hindsight, it is pretty much changing nothing on the inside and expecting exterior changes to be enough...people last years doing this and i met a guy who had been like this for 20 years...as miserable as anything but not drinking...i could never keep this up for more than a few months at a time before it became too much and drank again...
