If you have a small CD player and headphones, you can try this CD...Sound Sleep by Kelly Howell. It works. Before you realize it, you're off to dreamland.

A friend recommended Kelly Howell CDs to me years ago. I have a few and find them to be very relaxing. My bedside radio is also a CD player and I've got a small set of headphones that plug into the CD player. I put on the CD, put on the headphones and before the CD is over, I'm asleep.
