Ever see an alcoholic give up booze voluntarily? A gambling addict give up the slots?
I actually have... when they decided to do it, but it rarely happens (as in almost never) without other life-changing events taking place.
I've seen people change. Giving up booze for me was something I did cold turkey - and I had become a heavy drinker. Motivation is everything... length of time of use etc is a factor... but motivation is the biggest factor.
Funny... we try to box everything into one box and addictions are no different. Some folks can quit and go back to moderate, some even being near booze can toss them off the wagon... depends on their personalities, their issues and a lot of other stuff.
