I have been struggling with high cortisol for as long as I can remember & trying to work out which of these two medications are better at lowering it? I had a ACTH stimulation test done by an endocrinologist a few months back following a high cortisol blood test for suspected cushings but was within range high normal & wasn't givin anything to help lower it, I'm just at my wits end with this, I don't sleep well at all & just feel constantly on edge, my mind is racing 100 miles per hour, can anyone give me some input or advice, would be greatly appreciated
