I had a bout w/ insomnia quite a few years ago, and this movie really does hit the nail on the head. Turned out worrying and stress were the cause, and I learned to relax and finally fall asleep. But this movie definitely brought back memories.
I can only hope Alan finally found some methods that helped him get some sleep. I've found that exercise, drinking warm milk or herbal tea before bed and not working right before bedtime really helps (try relaxing before bed by reading fiction or watching TV). I would also recommend he stop taking sleeping pills, though I'm sure the doctors have done that or at least managed his prescription better.
