Tako has driven me out!!!

I've put the cage of my rabbit at the end of my own room, it means I and my rabbit sleep in the same room. My new rabbit Tako has a bad habbit of making noise during the night - after midnight, around 1 or 2 a.m. Every night she scratches the cage and makes a noise which wakes me up, and not only once, 4 or 5 times during one night and this of course causes the terrible lack of sleep. I've heard that the volunteer lady, who had taken care of Utako for about 1 year, had let her go out of the cage and run around the room for the exercise very early morning - actually at 2 or 3 o'clock, so this midnight exercise might have become a habit. But I can't let her run after midnight, she needs to learn sleeping in the cage iduring the night. But at the moment I can't stop her making noises. and since yesterday I have slept in the other room for I found I could not stand the noise any more. I feel somewhat ... ridiculous about this situation. Why do I need to give up my own room for the rabbit??? I hope she'll learn to sleep or at least being quiet during the night soon...  X(
