See if you can journal about your activities during the day, evening, and night. Things you do first thing in the morning, food you eat, beverages you drink, type of exercise, etc. Also, the weather can impact adrenals and cortisol issues, and how much time you spend outdoors, exposure to sunlight, the seasons– there are circadian rhythm imbalances such as something called seasonal affective disorder, which usually happens to people during fall and winter… So many factors that could probably be pieced together if you journaled about them and then tried to solve the puzzle that way.
