I take 15 mg. of Cortef, but not Florinef. I take Synthroid for my thyroid, and human growth hormone by injection.

I, too, had all the symptoms (passing out, fatigue, weight loss, low blood solium, high blood potassium, etc) but normal ACTH stimulation test so I was sent back to the family dr. Nine months later I tested low for aldosterone (cortisol was still normal) so my dr. started me on prednisone and Florinef. So, don't give up-- sometimes the symptoms appear long before the lab tests show Addison's.
