Insomnia As An Imprinted Behavior

Hello. I have had insomnia since I was a child. Always having a difficult time going to sleep at night and staying asleep. Throuhout my life there have been periods where I was adjusted to being awake during the day and sleep at night, but always went to sleep very late. However, I would lapse back to a reversal of sleeping patterns. Awake at night and sleepy during the day.

Recently, I had an interesting conversation with my mother about my sleeping patterns. She informed me that while she worked during the day, my father worked nights and so I was asleep during the day until my mother got home and my father went off to work. My mother took care of me at night while she got what ever sleep inbetween.

This went on during the first two years of my life when my mother and father were together. I learned in psychology class that these first two years of a person's life are the 'imprinting' years. Whatever behavior instilled and exposed to a child during these years are the foundations to behavior that will last throughout that child's life.

Is there anything I can do to adjust? I'm trying very hard to get back to a regular day/night cycle and it's wearing me out. I don't take well to medications either so it makes it harder to find a method that will work.

If anyone here has any suggestions, tips, or advice, please send them my way. It'd be much appreciated.

Thank you
