Do you use an alarm clock to wake up in the am? I have a sickening habit of waking up every day at 5! Even on the weekend I get up between 5 and 6:30. I wish I could kill my internal clock, but no luck!
I use an alarm clock, but I set it on radio and keep it soft. I usually wake up at least 5 minutes before it goes off anyway! My husband is the opposite. I set my alarm for me to wake him up, because his is a load blaring horn-like noise that I just can't stand! I guess I need to be woken up gently...
