Right now, bedtime is usually 11:30 PM to 1:30 AM. I usually wake up somewhere around 7:30 or 8:00 AM and try in vain to go back to sleep for another 30 or 45 minutes.
If I didn't have to get up for anything, I'd go sleep around 2 or 3 AM and wake up at 10:30 AM. That's usually what happens on Saturday mornings.
I hate waking up early, but I like getting out and doing things early. Conversely, I like sleeping in, but I hate not actually doing anything until 12:30 or 1:00 PM.
