I don't follow you, you stopped taking steroids because you finished the course of them that was prescribed to you, or because you just decided that you weren't going to follow your Drs.' advice?
While I don't know how effective steroids are for AN symptoms, I can tell you that they are not some form of quackery. They are a conventional, commonly prescribed, treatment for AN symptoms. It's not simply a matter of "steroids are bad" and I don't think that is what anyone is saying here.
I know my Dr is prepared to prescribe them for me should my symptoms suddenly worsen and while the side effects from them aren't typically pleasant, they are temporary and I will take them if the situation warrants them. Being prescribed steroids for this medical condition does not mean your Dr is treating you as a guinea pig.
