I would say 99.9% your husbands adrenals are exhausted!
You will be able to find lots of info here to help you.
Many Doctors will not be able to diagnose as their tests only show up when a person has total adrenal failure ie Addisons...Adrenal fatigue/exhaustion is far more common, but still serious and very unpleasant.
There can be so many symptoms with adrenal fatigue..but all can relate back to the problem.
Don't start trying to detox t hough..the body must be built up with excellent nutrients preferably organic superfoods, rather than laboratory vitamins/minerals that are generally not recognised as real nutrients in the body.
But read through this forum you are at the right place.
