Right now my sleep pattern is pretty fucked. I just finished my education and ended my final exam with a solid 12 (A), so the past 6 days my class and I have been partying non-stop (tradition). Due to all this partying I only got 6 hours of sleep from Monday - Sunday. There where nights where I didnt sleep at all you can see. Walking around for 6 days constantly drunk (or at least not entirely sober) is a strange feeling. You know you have partied hard when being sober is a strange feeling. Oh well, but god damn, I have never slept as well (and long) like I did last night. Went to bed at 5:30 in the morning and woke up at 21:00 the same day.
Normally I go to sleep at midnight if I have to go to work/school the next morning, but since I just finished my education (=no more school) and I first start at my job September 1st, I now got 2 months of vacation and relaxation, so during this period I usually go to sleep at 1 or 2. How long I sleep though depends on the weather outside. Right now it's really hot, so I can't sleep that well at night because it gets so hot, but I can live with it.
