Mindreader,
I'm very saddened to read this post. To be denied a job for this is ludicrous. If you had continued to hide your problem and never voluntarily sought treatment to better your own life, you'd have that job right now.
First, Eskapa may not read this forum. Try contacting him through his book publisher (
http://thecureforalcoholism.com/ under the Media heading) or directly on Facebook (just search for Roy Eskapa).
Second, in this instance I suggest you follow the American way: hire a lawyer. Find out what lawyers and firms handle discrimination appeals for government jobs and give them a call.
