My sleeping patterns are like a baby's. I sleep 3-4 hours and wake up. All night long. I went to bed around 10 PM and now.....here I am! I'll go back to bed in an hour or so but be up again about 5 AM. I'm sure alot of it has to do with the schedules other people around here keep. Up early for work......I wake up, too.....no point in trying to go back to sleep until it's quiet again. At least I go back to bed after everyone has left. That's when I sleep the best......7 AM!!
