I had a problem with Fletcher last year waking me up during the night, and I have a dog door, so I know if he had to go, he didn't need to wake me up! Someone suggested maybe he was cold, and that was it! So, you might want see if it's that.
OTOH, Molly will whine for me to get up 4:30-5, and I know now, she just thinks its time to get up
I guess what I'm saying is, you need to figure out why she's getting you up
