Cortisol and sleep problems

Have been having disturbed sleep for a couple of years, wake up every night around 4-5am (or more often) with vivid dreams and feeling agitated. Also seem to strain my muscles overnight.

My saliva test results for Cortisol (which am guessing is the cause) were:

Morning: 22.9

Midday: 9.7

Afternoon: 9 - High

Nighttime: 4.2 - High

Don't understand why it should be within range in the Morning, would have expected you wouldn't want Cortisol to be too high on waking up but Genova give the reference range as 7.45-32.56...

Read the posting a couple of days ago, lots of good info, so have Epsom Bath Salts and phosphatidylserine on order. Any advice on how much phosphatidylserine to take, time of day, for how long...

Already following diet recommendations and my stress levels are only moderate.

tyronecvc, it's likely the high night time cortisol which is disturbing your sleep. Google 'Adrenal Cocktail' and try it at bed time to see whether sleep improves.
