I have suffered from sleep issues for years. I believe we may have finally found the reason for my odd sleeping habits. Here is an article from healthcommunities.com that goes into great detail as well as how to treat it:
Delayed sleep phase syndrome is characterized by the inability to fall asleep before early morning (i.e., midnight to 3 a.m.) and difficulty waking in the morning. Patients with DSPS usually are able to fall asleep when the body signals that it is time and sleepiness does not usually occur before this delayed period.
In some cases, instead of interfering with daily activities, DSPS may suit the individual’s lifestyle. If DSPS severely interferes with an imposed schedule, subsequent stress and anxiety may cause sleep onset insomnia. If a person realizes that it is important to sleep at a certain time and attempts to sleep before the body’s sleep phase occurs, severe symptoms such as excessive daytime sleepiness, fatigue, and altered eating habits may develop.
