I know I'm replying to my own quote but don't feel like editing---anyway what might work for this and research is minimal is blueblockers sunglasses if you're going to be in the sun. There is some evidence that it's actually the blue wavelengths of light which are responsible for regulating our moods in SAD and maybe even bipolar so its worth a shot if you can't sleep. They can also screen the blue light from electronic devices which tends to make you more sleepy at night. Anyway worth a shot.
