Time-Turner and the utilisation thereof

chazpure says in her latest post that she wants a time-turner to get all her writing done, which got me thinking. Hermione used her time-turner in PoA to get to her extra classes, and that left her tired and sleep-deprived.

You know what? If I had a time-turner, I damn sure would use it to get extra sleep. I can so picture myself waking up to the shrill sound of the alarm clock, and, instead of pressing the "snooze" button, grabbing my time-turner and propelling myself a few hours back to get more sleep.

That leaves the question whether I would encounter my sleeping self lying in bed beside me. Ah well. I wouldn't mind. I definitely would share bed with myself. Now there's an idea...
