You have to hit 'rock bottom'

 Here's why this is dangerous: If we wait until a person "bottoms out," it could be too late to help them.
Every person has a different "bottom." For some, it could be getting arrested or becoming homeless. For many, it's much less dramatic -- losing an important personal relationship, being confronted by family or doing poorly at work or school.
There is little evidence that the level of consequences a person accumulates before seeking help is related to their chances of succeeding in recovery. It's better to get help early than to hold out for the perfect desperate moment.
