This is typical in adrenal fatigue. Your diurnal rhythm is messed up. You get a small boost of energy in the early morning, followed by fatigue that follows you through the whole day...but you still stay awake until very late at night because around 11:00 PM as part of your bodies natural defense mechanisms your body gives you a surge of cortisol that lasts you until around 1:00 AM. It may feel nice to have that extra energy late at night... but by staying up you only deplete your cortisol levels further and screw up your bodies diurnal rhythm.
Fix it by doing the following:
* Ensure you are in bed around approximately 10:00 PM. Take some 5-htp, melatonin, and ashwasghanda to help you fall asleep.
Try to wake up around 8:00 AM, and start the day off with a glass of salted water, 2,000 mg of vitamin C, vitamin b5, licorice root, and adrenal extracts. Be sure to eat a breakfast that is equally high in fat, protein, and carbohydrates. Shortly after go for a walk, or do some light excercise to help stimulate the cortisol in the morning.
Repeat in the afternoon & again in the evening if fatigue persists.
Remember... every hour before midnight is equivalent to two hours of sleep. The sooner you get into bed, the better and more refreshed you'll be the next day.
