Nighttime (3am - 5am) and less than 6 hours -- Here's mine! I average 6-7 hours of sleep everyday, except the weekends now I just tend to sleep through the whole damn thing. I catch up on all sleep over Saturday and most of Sunday, but hopefully that will change by June, where I can be back on a normal schedule for good.
Over the last week I've been going to bed at 2am-3am and waking up at 9am-10am. Big change from my usual rise at 11am-1pm.
