I have a weird cycle I go thru every few months. Ill sleep normal I mean passed out by midnight every night up at like 9am wakin up before my alarm goes off wide awake sort of thing. Then Ill slowly start sleepin longer Ill hit my snooze Ill turn it off or just ignore it completely (winamp playin streamin radio not an annoying alarm) Until Im wakin up at like noon or 1 or 2pm then I of course start stayin up later which makes me sleep later and thus makes me stay up later
Next thing ya know Im gettin up at like 6pm and sayin up til 10am then I have to force mself to not sleep for an entire day or so to try to reset and thus it starts all over
