Annoyingly, I second what they say at these centres, the person has to call and make the step.
It’s hell for us as their family because we’re the only ones that feel the consequences of what they’re doing.

Otherwise you’re the person doing all the running around for someone who isn’t remotely interested in being clean…it’s like taking a pill for another persons headache.
