For me it depends on what I work the next day. If I work the morning I usually sleep from about 1am-7:20am. If I don't work in the morning I go to sleep between 1 and 3am and will sleep until between 12 and 1pm. I just can't help it on my days off or days I don't start work the morning. I try to get up earlier but I can't. I end up just laying on the couch and falling back asleep.
