This is a really good link for adrenal symptoms - you can have adrenal fatigue (which is serious in the later stages) without having them "crash" - which is actually Addison's, which is life threatening. I was at the bottom of stage 3, starting to enter Addison's 2 years ago. Here's that link:
/www.drlam.com/articles/adrenalexhaustion.asp While some doctors claim they can determine this from blood tests, saliva testing is the only accurate test and it need to be tested 3 or 4 times in one day for an accurate reading of how your adrenals really are doing - blood tests are done only one time during the day, so they (like collecting saliva only one time) will only have the reading for that time period and your adrenals may just happen to be producing the right amount of coritisol for that specific time of day, yet no other time of day.
My last doc thought she could tell by blood tests, and every time I asked about
saliva testing, she just told me that she understood the blood tests well enough - wrong! I have been in treatment for adrenal fatigue and hypothyroid for 20 months under her care, and I improved very little - I only stabilized. Once I fired her (just a few weeks ago), I went back to what I used last time I was dealing with this, and although I wasn't as bad, I'm still seeing improvements where I had not under her care. This is why it's so important that we advocate for ourselves - doctors think too highly of themselves too often. Had I stayed under her care, who knows when I might have finally started to feel better?
