The keys she puts into a Kitchen Safe - a jar that locks for a specified amount of time. She sets it at 7 hours, puts the keys to the padlocks in, closes the lid and presses the button. After a 5 second countdown the locks engage, and the keys are unavailable to her for the night.

Then she takes out the chain that runs though the bed frame, weaves both ends through the ring on her collar, and lock them to her wrist cuffs. Now both her neck and hands are locked to the top of the bed, and the more her head moves away from the position on her pillow, the more her hands are pulled up to her throat.
Then there is nothing left to do but sleep, until the jar unlocks in the morning.
