I found out I had a very severe case of AF 16 years ago, and spent many years recovering from it. My adrenals started getting better about 3 years ago, and are now about 95% recovered. I used to post a lot on this forum when I was still recovering from it. Now, I only post occasionally.
One reason it took me so long to recover is that I had and have a lot of other major health issues that overlap(ped) with the adrenal fatigue.
