My scenario has been since my situation arised, that I will go periods of getting up early and going to sleep early which I very much prefer. But it will instantly change, and I will gradually stay up later and later, rise later and later, until...

I may be on to something. Until I have another mixed up, all over the place, up and down, angry and mad, and depressed melt down. Trazadone did well to get me sleepy at first, but I think it's losing it's effectiveness. And in the subconscious mind, I don't want to go to sleep because I have to wake up to the same life tomorrow with the exception of having one day less in front of the horse than riding in the back of the cart.
