I tried a juice fast and felt ok for about 4 days but then my metabolism shut down and I became very cold, non-stop shivering no matter how much I put on, and exhausted, could barely get out of bed.

I also had a problem with liver flushes. After I did about three, I had the same reaction. So if there is any adrenal question, I would take it slow.

to the best of my knowledge, most with adrenal fatigue would not benefit from a fast, or cleanse. the logic being that the adrenals are heavily involved in these processess. therefore, you may end up taxing already weak adrenals and making them even worse. any kind of reaction like a die-off, or a release of toxins in the system, would make the adrenals respond. again, this would only make weak adrenals weaker, or, in other words, a weak system can't handle this sort of thing properly. it seems that the best thing to do is to slowly strengthen and recuperate adrenals, before anything like that. i have been wanting to do some parasite and bowel cleansing, but i know i need to wait at least another 2-4 months when my adrenals "should" be back to normal, from the rate i've been progressing. i'm not going to rush it. i'm pretty sure that Liver Flushes taxed me too much. they didn't cause my adrenal problems, but they caused my weak adrenals to come to the forefront of my health issues and life.
