Reverett, that is the time of day when our dopamine is highest. Its true of me and I bet its true of everyone, Then we eat breakfast which will contain things that suppress our dopamine. Then we dont feel as pleasurable and have less energy and less of a sense of well being. My dopamine is lowest at night but evidently my serotionin is in a reverse order because in the morning , back in the days I had depression, it was always worse in the early morning, steadily getting better throught the day, until late night it was the best.
So EVerett, what you are saying to some degree verifies the high dopamine diet for Parkinsons, not conclusive , but our first piece of evidence outside of my observations of myself.
