I could see it building habits that persist even when no longer using the drugs. They've found other things to fill their time instead of eating, and things which would previously trigger them to start eating now trigger them to do other things.

There's of course a risk that when they stop the drugs that hunger will drive them to re-establish those habits, but now that they have new habits that fight that hunger they are in a much better position to resist it than they were when they'd initially established their eating patterns.
