Hi, 'psychophysiological' is an awfully big word for anxiety and an obsessive mind. I bet - if you are like me- this overactive mind is not just troublesome at night. I found 2 books helpful: Gayle Greene: Insomniac (infuriating because there seems to be no medical help), and Siegfried Haug: I Want to Sleep - Unlearning Insomnia (Very good and readable if you want to take control of your runb-away mind; probably most helpful if you already had some exposure to therapy)
