I go to sleep around 12 or 1 am and get up around 9 or 10 am. So, I guess that's enough for me. Sometimes I get up early and during the morning and afternoon, I get sleepy.
I usually go to bed at 12-1am almost everyday, sometimes I like to go early to bed like at 11pm. I always wake up at 7:30-9:30am. I always wake up early. I rarely wake up super late like 12am.
