Oh dear, another cocker with a possible auto immune diagnosis - this is not good.... however, its great that you may have diagnosed Addison's very early on, and that Vegas is not having an Addisonian "crisis" which is very serious.
Please let us know what the ACTH results are - if you can get pre and post results that would be very interesting.
If you need any help - you're more than welcome to join my AI support group - there are lots of Addisons folks on there.
