It sound so familiar to me. It was when I was studying at University. I came to parents' home for a holidays and was hoping to rest and have fun with friends. I also needed to write at least some chapters of my coursework, but I was sure that I would find a time for this later. And I didn't know why, but I couldn't sleep at night, even if I came back from party at 4-5 am, I couldn't sleep, but I really wanted to and needed to. When I was lucky I felt asleep for 2-3 hours, but laying in bad and praying for sleep was terrible. Without knowing a reason I decided to write a coursework, and I wrote only introduction - but the miracle happened - that night I fall asleep at 8pm, and was sleeping soooo long and soooo good. I want to tell you that the reason might be in your conscious - maybe you are worrying about something or need to do something. Now, as I already graduated and work at services company
, my conscious
feels calm, mostly, but from time to time sleep issues coming back, and I'm always try to figure out what is going on in my head :) Hope this helps you too.
