I use these books for exactly the same reason! I had a really hard time falling asleep until I discovered that putting a Discworld novel on in one earbud was enough to silence the voices in my head long enough for me to fall asleep.

It used to be that I'd take an hour or more to fall asleep, now I'll often be asleep within one 5-minute run of the sleep timer.

I finished Discworld and have moved on to Stephen Fry's Sherlock Holmes, which has much the same effect.
