Your symptoms are almost exactly like mine. The brain fog was because I was given all kinds of medicine to treat my symptoms, but when they found out I had secondary adrenal insufficiency caused by Advair and Nasonex, my doctor took me off of a lot of the meds. I take Bystolic and another med for my high blood pressure and fast heart rate. They will try to keep me on just Bystolic soon.

I also can't work right now because I have had spine and rotator cuff surgery in the past year, and I have no stamina. I can't exercise, take stressful situations, or any loud noises. They say it will take a year to get better, but I will never have the stamina I used to have. But at least there is hope.
