I have worked in the medical profession all my life.. I say HELL NO ! there is no reason to disclose. I have seen nurses that are drug addicts come to work stoned or hungover so bad that they would ask ME if they pulled the right medication to give patient X ..

Oh the stories I could tell. You have an illness that is well controlled and you are able to function and perform your duties. If it were me I would NOT disclose a damn thing.

Just my opinion.
