Is it normal that sometimes i sleep for 2-4 hours and sometimes 10-12 hours?
I'm worried about my sleeping cycle. Last last week, I had a sleepless night and had no naps that afternoon. I felt like I'm drunk. It happened again 2 days later and I can't stand my tiredness so I cut my last to subject that day and took a nap.
Then there were times last week that I'd sleep for 3 hours if not 2 hours.
And when I sleep at nights which have no classes the next day, I sleep for like 10-12 hours. Yesterday, I slept at 12:30 a.m and woke this afternoon 10 minutes before 2.
Usually, I think, during school days I sleep for 4-5 hours a day and 6-8 hours a day during no-class day. But it changed since last last week. Now, I can say that I sleep for 0-3 hours a day during school days and 10-12 hours as day during no-class day.
I just wondering (and worried) if this is normal? Is this going to affect my health in bad ways? How?
