Our bedroom is in the northwest of our flat. The walls are light pastel, the position of the bed enables my husband to sleep with his head pointing east (his tien yi direction) and the shade for the pendant light is rounded and directs light up rather than down over the bed. The bed is not under a window nor is the door directly opposite the foot. There is room to walk around reasonably comfortably. My husband suffers from occasional insomnia which is quite severe when it does occur. Are there any other enhancements I can add to the room? Do I have to get rid of our Edward Hopper picture, which is an interior but shows the sea? I'd be really grateful for any advice on this, as I am coming to my wit's end! Thanks, Robin
