Oh come on now.....
No one should be up at 4:30 am on a Saturday, unless you're working!
Does anyone else have difficulty sleeping? Many nights I wake up every 2 hours or so. I usually manage to fall back to sleep only to wake again. When this cycle starts I usually am wide awake for good between 3:30 and 4:30 in the am. This is so annoying since I don't work in the summer and no that I need to stay rested!
I do have a Rx for Ambien and take that from time to time, but if I use it several days in a row I have a really hard time sleeping when I stop taking it. I am on O2 when sleeping at night, but still have problems.
