Here's a convenient synthesis of some sleep articles related to mental health issues:
http://www.psycom.net/depression.central.sleepdep.html
I recall reading that sleep undergoes 2 phases, lasting approximately 4 hours each cycle. You may be only sleeping one cycle rather than 2. Sorry I can't expand upon this, but from what I remember, hormonal differences account for whether you sleep the 2 phases and there is a delineation among sleep problems such as early rise (after 1 cycle) and delayed sleep syndrome where a person cannot go to sleep until very late.
