I have adrenal fatigue and hypothyroidism and lots of metal fillings. My adrenal fatigue has been high cortisol and I have just reduced it so now I am going on the home stretch of final repair of weak adrenals. I have tried some of the things your mentioned and I think they might have put even more stress on my body. Fasting will also a lot of times stress your adrenals. Nine months ago I tried Liver Flushing 5 times over the space of several months with no relief. My digestion kept getting worse. If I ate a fatty meal it seemed really hard and slow for my body to digest. I would feel bad for hours after I ate and started getting headaches every time I ate. I finally started focusing on what my body needed to heal the adrenal fatigue instead of the symptoms seperately. I started with 7 keto Dhea and added other supplements like B complex three times a day along with other supplements to lower my cortisol and support my adrenals. The other big thing that helps my digestion is Rhodiola. 7 keto dhea help my digestion but it took about three weeks. Along with supps I am doing several things to relax and calm myself. Stress is a big contributor to your body not being able to tolerate and detox on it's own. Also I make my own kefir and Kombucha. Kombucha is a great liver detoxer. Over the last 2 months I have healed very quickly and my candida has gone way down.
