I prefer going to bed at 5-6 pm or earlier, if I can, and then wake up at roughly 1-2 am and continue my day from there on. However, currently my schedule is rather normal, as I go to bed at midnight and wake up at 6:30 am during weekdays. On weekends I just kinda stay up until roughly 3-6 am, depending on how tired I have gotten during the week and wake up whenever in the afternoon.
