If you're not getting enough sleep at night, you'll end up tired and run-down. If you've tried other ways to get a good night's sleep, but nothing really works, then here's a new idea to test out - Body purifying herbal foot pads from Gaiam.
These foot pads can boost circulation and help remove toxins from your body such as nickel, arsenic, and mercury (which might be the reason you can't sleep in the first place).
You place them on the arches of your feet and wear them while sleeping 8-10 hours. According to the principals of the alternative practice of reflexology, trigger points in the feet affect the rest of your body. When the reflexology points on the arches of your feet are stimulated, it can help you sleep.

Whether you believe this sort of thing works or not is up to you, but they could help you catch up on your zzzz's. The footpads come in a 10-pack and can be purchased from Gaim directly for $24.
