CHQ: SUBJECT: Does my circadian rhythm need adjusting? If so, how?
  MESSAGE: I had a saliva test last July, which showed my cortisol level at 9 @ 6:30am, 5.1 @ 11:30am, 4.2 @ 4:30pm, 3.3@ 9:30pm. I wake frequently during the night and my brain seems to engage in much thought, making it difficult to go back to sleep. I wake well before the 5:45 alarm and drag myself out of bed. I am exhausted all day and can fall asleep at day or evening events I have seen endocrinologists, in addition to my GYN and primary care dr., all of whom tell me all my blood tests are normal. I take 2 sport yoga classes and a Qi Gong class weekly. I was a young 65, but at 66, the lack of sleep has finally caught up with me and I feel much older than my 66 years. I feel lethargic and heavy-chested. I want my life back. I have never seen or read anything about how or where help can be found. Can you help?
Summary: Where can I find information on low cortisol levels, including symptoms, causes and treatments?
