i never really thought that irregular sleeping patterns were a problem for myself up until now. right now im 24 and looking back wheni consider my sleeping patterns over the years they have been completley erratic. in high school and college it seemed like the normal thing. the patterns would range usually as follows.
in the beggining of the year from say february to april i would go for 2-3 week periods of only sleeping in 4 hour shifts. as the week progressed that number would fluctuate from 4hours at a time to 3 and then two and then a big crash at weekends. naturally i would stay awake for shorter periods at a time as well. and this functioned for i had irregular studying patterns and my classes were at odd times aswell. closer to examinations i would stay up for days at a time only sleeping 5 to 6 hours just before an exam and just after them for about 2-4 hours. [exams were usually in the morning]. an exam period would last for about two weeks of 3-6 papers strewn our over the fortnight.
end year from about august to november the patterns were different and more regular. i would sleep regular hours and wake up in the morning sometimes at 6am sometimes later in the day say 8am or 11am even. my day would function normally and i would sleep at say 10 or 12. never before 9 though. i was also more healthier and fit end year, and played more sports or was more active.
now i am out of college and i dont work. it is february and im feeling the beggining of what would be a study cycle. my patterns are uber irregular. i started staying up till about 3 and waking at 12. now its slowly changed to where now i stay up all the way until 11am and wake up at 6pm. any knowledge on this would be appreciated.
