As the intervention progresses, start assuming control of the entire situation. That usually means changing everything you have been doing and how you have been interacting with the person. Often families have been providing money, food, shelter, modes of transportation and cell phones. You must be prepared to gain control over the person’s actions and decisions by eliminating this support and letting him know that his only option is to choose rehab.
Once you have all these preparations and adjustments planned out, now it’s time to roll into the intervention itself.
