...CHANGE...
To me rehab, becoming sober and/or changing habits/behaviors is all about change. By becoming sober one will have changed their ways. They will have changed their habits and hopefully their attitude/mindset. I think once people want to change and realize they will have to change then rehab or sobriety becomes that much easier.
Change is tough for anyone. Just look at some of the problems with daylight savings time. Many have trouble adjusting and some of that trouble is not making a real effort to adapt.
