Fair enough, I don't mean to say that I'm not a proponent of exercise, or having a cold bedroom, or any of the other standard pieces of advice. I follow them all by habit at this point.

What I mean to say is that first things first. There are lots of well-meaning advice we can give to people suffering from insomnia, delayed sleep onset etc etc. Most of it will only work if it helps fix anxiety. Awareness of this can be very helpful by itself.
