Oooops
Let me try this another way....
The world is full of adult children who expect to be taken care of by other people.
The only reason for an able adult to lay on a couch and watch TV all day, every day, is because someone, somewhere is taking care of their business, for them.
If you stop fixing it for them, they will either find someone else to do their bidding or eventually figure out that maybe, just maybe, they need to take some responsibility for themselves.
And none of this has anything to do with addiction.
I am the mother of an addict and the monkey belongs on the addict's back.
