Who Needs Sleep?

I have found them helpful, although these days I generally just want silence. If you don't want earbuds and you don't want a CD player/clock, you could always get an official "sound soother" machine. I have this one: http://www.amazon.com/HoMedics-SS-2000-Relaxation-Machine-Nature/dp/B000F3QG0U/ref=sr_1_1?ie=UTF8&qid=1329197101&sr=8-1 and it only has one green light that could easily be covered up with duct tape and/or a towel. It has several different settings - I like the ocean waves one, but there is also a generic white noise one too.
