when one stays up later and later to get back on a normal sleeping schedule that will work for going back to school.

- the summer sleep cycle usually occurs during prolonged periods of time off school.

-one will choose the summer sleep cycle method over going to bed earlier because going to bed earlier just never seems to work.
Oh man, school starts in a week and i've been going to bed at 5:00 in the morning and waking up at 4:00 in the afternoon. Oh well, ill just do a summer sleep cycle to get back on a normal sleep schedule.
