Constantly anxious, feeling 'plastered to the ceiling', can't fall sleep, afternoon fatigue? Hormones out of wack..? Probably. But in the overall picture, this can be your adrenal glands (responsible for hormone production, and our stress hormone, cortisol) on overdrive. Unfortunately we can't function too long like this, and our adrenals can eventually be so burnt out (e.g. can't stay asleep, moodiness before meals -'hangry', crave carbs/sugar) that our cortisol level in the morning looks like it does at night. That should not be. Cortisol is supposed to wake us up, and decline throughout the day, til melatonin (sleep hormone) takes over to get us sleeping. Prevent progression of adrenal fatigue, or address if this is how you feel, by having frequent, smaller meals, protein and healthy fats (balance blood sugar), do things you enjoy, and gentle exercise.
