Anal insertion for medical reason

In short. I have an medical condition that requires using anal dilatator (which is basically butt plug) in order to stretch my sphincter.
Some of you maybe see the problem right away: anal stimulation is one of my unhealthy desires.
Even if I can control myself not to M, it still drags my thoughts back to unhealthy pattern.
Someone may suggest just quit it, or do it for necessary period of time and then quit, but it's long running problem that gets worse everytime i stop using the dilatator.
Any suggestions, experiences?
