Night Owl??

I have recently asked myself that question since for the past few weeks I am up way past a reasonable sleep time. I am not too sure what has caused this situation could it be some sort of anxiety I am having and not know about it? It cant be the coffee because I have stopped drinking it before this started. Maybe I should treat myself like a baby and take a nice bath drink some warm milk and snuggle under the covers...Or should I just free my mind and relax, relate, and release what ever has me turning into this NIGHT OWL....
