Hi Carey, I have symptoms very similar to yours. I never got my adrenal hormones tested, though. I also have low body temperature, too, and have read that it can be caused by adrenal problems. Have you ever heard of the book The Schwarzbein Principle? I just got her second in the series and it explains so many things and has a diet to help you get better. I have been doing it for a couple of days now, and the first couple of days I felt worse, just as she predicts might happen. Yesterday was the first day that I didn't have a piece of fruit since I started the diet, and by yesterday afternoon I started to feel better. Today I am still tired, but I am getting more done. If you do read her book you will understand why the mastercleanse made you feel worse. She also has a website.
