Hi Sue, the siliva test will tell you more about your cortisol, adrenal fatigue, diabetis, and DHEA. My cortisol was very high after lunch, very high at midnight, and fell very low in am. Insomnia is caused when the your Cortisol goes very high. In the am when your Cortisol, goes very low, it's very hard to get going in the morning. In fact until my Cortisol rises after lunch to above normal, I really can't get going. The DHEA tells the doctor if you are actually in adrenal fatigue. My overall score was 60 (below 50 is normal), which tells the doctor I have Adrenal Cushing Syndrome/disease - not yet diagnosed. Adrenal fatigue can cause your body litterly to close down. Hope you have a good Endro. I am hoping for a referral to an Endro, one of the best Adrenal Cushing Syndrome specialist here in Canada (there are not many).

Hope you get help and answers soon.

Hugs
Gerri
