The way insomnia goes is you are neurologically incapable of producing the hormones necessary or you have an increased amount of neurological electricity that causes manic episodes, seizure, extreme stress, even narcolepsy. You MUST get sunlight!!!at least 30 minutes of bright sun in contact with the eyes, face, head, and skin. Let me say first that a tan is not the objective, you do not need to lay out. 15-20 minutes in the early morning will kick off your circadian cycle to respond more intensely in the form of sleep as light cycles change. If you are offset by your plants cycle you should set a time in which 2 hours prior to your ideal bedtime you DO NOT work in the garden any longer. I found help taking B-12 intravenously as well as high levels of D vitamins. Alcohol is best avoided until sleep returns to healthy levels. I know it is great....but it is terrible for proper sleep. Increase protein quality....try a protien shake 1st thing in the AM. The brain needs protein to repair itself and if you are not sleeping it needs even more. Godspeed.
