Primary or secondary adrenal insufficiency? If primary, you should perhaps also be on fludrocortisone (Florinef). Salt cravings, Na/K imbalance, low blood pressure & gray-outs... you mention 3 of those 4 which point to primary AI and possible need for Florinef to support that issue. This sounds like what your Dr. is checking for. If he/she doesn't bring that medication up in your next visit, you should. Hope you get to the bottom of things,
