Incurable Insomnia? You might have a circadian rhythm disorder!?

Many of you sound like you have delayed sleep phase, impossible to fall asleep until much later than you want to, but if you wait until late, you fall asleep fast and sleep for 8 hours no problem. If routine, relaxing, don't work, please google DSPS! The two main things that have been found to significantly help with DSPS are bright light therapy, use of melatonin as a chronobiotic.
