There is a long list of conditions on the aviation medical application that require a yes or no. Are pilot applicants always truthful when it comes to checking the appropriate box? I don't think so. Some pilots deal stricly with their PCP on troublesome issues, but withhold that information on the medical application.

Just know that there are serious consequences if you are somehow exposed. I would also have a hard look at yourself and your attitude toward alcohol. You've been clinical diagnosed with alcoholism, yet you deny alcoholism and place responsibility on a flawed evaluation. Take care of yourself.
