Another possibility: I have had -,  ánd heard amazing results with the Nikken sleep-system: falling asleep more easily, no more tossing and turning, no more waking up in the middle of the night, no more sweats, waking up refreshed and bouncy etcetera. Even from people that hadn't had a good night sleep for years!               

Any Nikken -consultant in your area should be able to lend you one to try out. More expensive than a pebble, but if all else fails .....
